Chocolate Benchmarks are Back!

Thu, 03 Jul 2025 13:41:00 -0400

Nearly 20 years after I first wrote the blog post about making your own chocolate benchmarks, Bruce Bourgoine, Executive Director of the Maine Society of Land Surveyors, contacted me to ask if he could publish it in an upcoming issue of FieldNotes… The Monthly Newsletter of the Maine Society of Land Surveyors. Well, this big day is finally here! A reprint of the blog post is available in the June 2025 edition.

Washington, DC Historical Benchmark Tour featuring Dave Doyle

Sun, 02 Mar 2025 19:03:00 -0500

Today Rich and I came across this awesome video featuring Dave Doyle, former chief geodetic surveyor of the National Geodetic Survey, giving a tour of historic survey monuments in Washington, DC. We learned so much from his presentation, and we even bought the book (The Jefferson Stone, by Silvio Bedini) that he recommends in the video.

Follow along by checking out the NGS datasheets linked from the map below. The waypoints are numbered in the order in which Dave visits them in the video. You can also download a .gpx file of the markers shown in the video.

Florida USGS Datasheets Posted

Recently I came across some USGS datasheets from Florida posted on LABINS, Florida’s Land Boundary Information System.

Unfortunately they were all scanned as individual pages in .tif format, so I downloaded all of the pages, converted them to PDFs, and georeferenced the quads.

Note that not all quads were available, and there are no datasheets for horizontal marks, only third-order leveling.

Joy of Geodetics

Sun, 05 Jan 2025 19:33:00 -0500

Recently while updating this website, I came across a resource that will be useful to other recreational survey mark hunters:

Joy of Geodetics: An 8-Part Geodetic Survey Markers Educational Series, by Greg Shay of the United States Power Squadrons

While I have to admit that some of the official recoveries by the Power Squadron that I’ve come across are of … shall I say highly variable quality (to the point that it has become a bit of an inside joke), Mr. Shay has done a great job here of describing the different types of survey markers and how they are used, how to search for them, and how to submit observations and photographs to the NGS database.

The titles of each document explain the contents pretty well, but Mr. Shay also provided an outline for even greater detail.

Accessing PA Historic Type 10 Maps

Sun, 15 Dec 2024 08:03:00 -0500

I often refer to PennDOT’s historic county maps, specifically their “Historic General Highway Series” Type 10 maps ranging from the early 1900s through the early 2000s. Their website was redesigned recently, and while the Type 10 maps are listed, the links included in their listings do not actually bring up the maps. Here is a process for accessing the maps until the issue is resolved.

Note: There is a similar issue with the current Type 5 maps; I don’t generally use these, but if you do and would like me to post the information about accessing them, please comment below or contact me via the form in the footer.

I appreciated receiving an immediate response to my request for help. The person who wrote to me from PennDOT stated:

Specific Type 10 Historical maps can be accessed with the following 3 step process:

Go to https://gis.penndot.gov/BPR_pdf_files/Maps/Type_10_GHS_Historical_Scans/Adams_1916.pdf

Find and copy the filename for the map you want to access from the attach listing.

Change the filename portion in the URL to the filename of the map you wish to access (e.g., change “Adams_1916.pdf” to “Washington_1990_Sheet_1.pdf)

Cumbersome, but a relatively easy way to access Type 10 Historical maps until the issues with the page are resolved

I used that information to create the list of links below. (If you want the text file itself, or you can download it here: Type10_Historical_listing.txt)

Magnetic Stations, Part 2

Sun, 10 Nov 2024 19:03:00 -0500

Returning to Results of Magnetic Observations Made by the United States Coast and Geodetic Survey in 1914, I researched two other magnetic station locations that are close enough to me that I might be able to search for them, although they are both long shots.

The first is:

Easton, Northampton County.-The station of 1910 was reoccupied. It is in the northwest part of the March athletic field of Lafayette College, 38 feet southeast of the concrete wall surrounding the field, 12 feet northwest of the outer edge of the running track, and 1 foot southwest of the continuation of one of the sides of the baseball diamond. The station is marked by a marble post 6 by 6 by 15 inches, lettered U. S. C. & G. S., and buried with its face flush with the ground. The following true bearings were determined in 1914:

Tower of courthouse ………………………………………………… 23 30.0 west of south

South College ……………………………………………………… 36 44.8 east of south

Northwest gable of fraternity house ………………………………….. 65 25.5 east of north

Given all the changes that tend to accumulate on college campuses over the years, it’s unlikely this station still exists (or is findable). But it’s worth a look, particularly if I’m in the area.

March Field still exists, although Google Maps doesn’t label it as such (Waze does - and a monument to “March Field” is visible on Google Street View). PennPilot imagery from 1938 indicates that is has changed size a shape a bit over the years, and new buildings now surround it. But the old imagery depicts the baseball diamond, which may help in determining the site of the station.

Using the bearings provided, and assuming the surveyors used the obvious high points on the Northampton County Courthouse and South Hall, an estimate of the station coordinates is 40.698472, -75.21125. This is on the site of the former Olin Hall, built in 1956-7 (now refurbished and incorporated into the Hugel Science Center, circa 2001). So assuming these bearings are correct, it looks like the station is probably gone, or at least covered by buildings that were erected long after this document was published. But there is always a chance, and I would love to check it out!

Google Map

This one also intrigues me:

Laporte, Sullivan County.-Observations were made at a point about one-fourth mile north of the center of town in a pasture lot belonging to Mr. McFarlane, lying on the west side of the highway to the railroad station, and just north of a lot containing the ruins of a schoolhouse burned down about 1906. The point is 230 feet west-northwest of the gate to the pasture, 110 feet east of the edge of woods along a creek, and 190 feet south of a maple tree 18 inches in diameter which stands at the corner of the fence to the school lot. The point is marked by a natural outcrop of rock about 3 feet by 3 feet in area, and having a magnetic station disk cemented on to this rock. The following true bearings were determined:

Steeple of Episcopal Church (mark)…………………………………. 5 58.1 west of south

South gable of red frame house, one-fourth mile away ………………….. 61 57.6 east of north

East gable of barn on hillside about 1,500 feet away ……………………… 49 32.0 east of north

This one is very difficult to determine! Right now my best guess, based on nothing but going back and forth between the description, PennPilot imagery, and modern maps, is somewhere around 41.4310285, -76.490615. I will have to check it against the bearings but a preliminary look doesn’t seem to work out.

See: https://sites.rootsweb.com/~pasulliv/churches/Adona.htm (1965) for discussion of the church(es). The history is complicated but based on that site, it seems that the old Methodist/Episcopal Church later became the Community Hall, also used by the fire company in the 1960s. I think the address is 346 Muncy Street (41.422826, -76.494161).

There are no available historical USGS topo maps from before 1934, and the online historical road maps (the earliest of which is from 1915) don’t show much detail. This map: Topographical map of Sullivan Co., Pennsylvania, 1872 is interesting, and references a McFarlane property, but otherwise doesn’t seem to be of much help.

I haven’t been able to find anything else online to help me pin down the locations of any of the reference points other than the church. Perhaps a trip to the Sullivan County Historical Society to view their map collection and speak to the folks there will help.

Magnetic Stations, Part 1

Thu, 07 Nov 2024 20:39:00 -0500

I received three documents from Harry Nelson of MaineDOT concerning magnetic stations. He states that “The description of magnetic stations are not published by NGS other than in these publications.”

As described in Uses of Magnetic Stations (U. S. Coast & Geodetic Survey Special Publication No. 213 from 1937), magnetic stations provide known points at which magnetic declination can be measured and tracked over time.

The first document provided by Mr. Nelson, and the only one that lists magnetic stations in Pennsylvania, is Results of Magnetic Observations Made by the United States Coast and Geodetic Survey in 1914.

This station, in Hamburg, PA, might be possible for me to find:

Hamburg, Berks County.-The station of 1910 was reoccupied. It is in the western one of two circular plots near the center of the Union Cemetery, belonging to the Reformed Lutheran Church, about one-fourth mile from the center of town. The station is 6 feet west of the west edge of the driveway, 40.7 feet west of the southwest comer of the base of the tombstone of Stephen J. Smith, 49.6 feet south of the south face of the base of the tombstone of David Keller, and about 170 feet south of the gate of the cemetery. It is marked by a marble post 6 by 6 by 24 inches, lettered U.S. C. & G. S., set flush with the ground. The following true bearings were determined:

South gable of stone farmhouse one-half mile away (mark) ………………. 20° 37.6’ west of north

Cupola of barn 800 feet away………………………………………… 60° 48.8’ east of north

When I first looked at the map, I couldn’t even find the circular cemetery plots. At least according to Google Maps, there is no longer a Union Cemetery or a Reformed Lutheran Church in Hamburg, and at first glance I didn’t see any obvious circular plots in the large cemeteries I saw in town. But I used FindaGrave.com to look up the graves of the two people mentioned in the description, and the coordinates of those gravestones took me directly to the site.

My best guess at the coordinates is: 40.557284, -75.976726:

The Benchmark Hunting Section of Geocaching.com is Gone

Thu, 05 Jan 2023 09:25:00 -0500

Yes, it is the end of an era. Groundspeak has removed the Benchmark Hunting section of the Geocaching.com website.

I discovered this in a roundabout way. While doing some historical research yesterday, I brought up a geocache page but could not find the link to search for nearby benchmarks. I went to the community forums, and a search there brought me to a thread that announced the “retirement” of the benchmark hunting section of the website, effective January 4, 2023. Why am I only finding out about this now??? I thought.

As I state in my post to the Geocaching.com forums (copied below), I do understand the need to move away from legacy code, for any number of reasons. However, there are two aspects that bother me far more than the overall decision made by Groundspeak.

The implementation of the “retirement.” I can’t think of another example of a popular website that has retired a service (and worse, DELETED THE RELATED DATA AND ALL ACCESS TO IT) basically without warning to many of its users. Google has sunsetted about a million apps in recent years, but you always hear about it constantly and via many various means long before the end-of-life date. Same thing for other SaaS/cloud services and social media apps. In this case, Groundspeak did not send a single email about the end of the benchmark hunting section of their site. They relied solely on a post in their community forums, which many of us do not regularly read. Related to this, they should have posted a deprecation warning on each benchmark page so it was clear to anyone who was actively using the pages that they would be going away. (This is not onerous. It requires a single update to the template from which the benchmark pages are generated.) Again, this is just standard practice.
I am most upset (see capitalized phrase above) about the fact that Groundspeak has apparently taken the unfathomably destructive step of actually deleting all user data related to benchmark recoveries. As someone who occasionally wears a digital archivist hat, this is unconscionable. For over 20 years, users of Geocaching.com searched for and documented benchmarks and contributed their findings to what they thought was an ever-growing database that is still in use (or was, until yesterday) even by professional surveyors. It’s simply unfathomable in this age of cheap data storage to not at least allow the archive to live on somewhere. Groundspeak even had offers from outside developers to accept and maintain the archive, which they dismissed with pathetic excuses.

So we are left with some crumbs to gather. Internet Archive’s Wayback Machine has saved my butt plenty of times in the past, and here they come (somewhat) to the rescue again.

The benchmarking home page (as of December 30, 2022) is available here:

https://web.archive.org/web/20221230041305/https://www.geocaching.com/mark/

The postal code search doesn’t work, but the PID search does, at least for many of the PIDs I have tried. Be aware that the images are not stored on the Wayback Machine. If you find anything at all, it will just be the text of the logs, and the titles of the images.

To go directly to a mark’s page, you can use URLs of the form:

https://web.archive.org/web/20221208090238/https://www.geocaching.com/mark/details.aspx?PID=[PID]

where [PID] is the mark’s PID.

Unfortunately, because I don’t see a way to view the marks a user has logged, you will need to know the PIDs of any marks you want to look up on the Wayback Machine archive.

The NGS Data Explorer (now NGS Web Map, as of November 2023) can help with that:

The NGS Map

I have also contacted the developer of DSWorld, NGS’s app that, among other things, interfaces with the NGS database for mark retrieval and recovery. DSWorld contains a function designed to bring up Geocaching recoveries, which now, of course, results in a 404 error. The developer will probably just have to remove that part of the app.

I will also have to update the Geocaching.com links on my website to point to the archived page in Internet Archive instead.

Now you may understand why I have put so much effort into documenting my recoveries on this website and linking to them from Geocaching.com. I want the products of my work to remain under my control, although I do understand the conflict between that desire and the accessibility provided by a shared site. I saw the writing on the wall many years ago when the neglect of the benchmark hunting section of Geocaching.com continued on through several website redesigns, ultimately leading to the benchmarking section being hidden in all possible ways. But this does not in any way excuse what Groundspeak did, nor does it implicate anyone else who continued to use the service as provided, given no explicit indication that their contributions would be removed without warning.

Contributing to the NGS database helps fill in these gaps, and it is important for those who take survey mark hunting seriously. I wouldn’t recommend it to all benchmark hunters, simply because many of them enjoy it only as a recreational activity—but that is fine, and in many cases their contributions are still valuable.

If you are at all interested in this topic, please also take a moment to read through the forum post to see just how much of a positive impact benchmark hunting has had on many folks’ lives over the past 20 years.

Release Notes (Website: Benchmarking retirement) - October 17, 2022

My post to that thread (which is quite similar to what I’ve written above) follows:

As someone who has searched for and documented well over 1,200 benchmarks over the past 20 years, it certainly was very surprising and disappointing to discover that the benchmark hunting section of Geocaching.com was gone without any warning to me. I do not regularly read the forums, so I had no idea this change was imminent. I only found out when I researched it after the fact. I receive plenty of emails from Geocaching.com about souvenirs and their latest promotions – would it have been that difficult for them to send a message about the “retirement” of the benchmark pages?

Another thing that should have been done was to add a deprecation announcement to each benchmark page, so it would be obvious to anyone viewing the pages that after a certain date, the benchmark pages would no longer be available. It’s just standard practice.

But apparently it’s too late for any of that.

I understand the need to move away from legacy code that has become a maintenance burden, hinders future innovation, and does not fit the current goals of the organization. Frankly, given the lack of updates to the benchmarking portion of the site, I expected this to happen a long time ago, and that’s why I began documenting my survey mark recoveries on my own website instead. But many people did not have that option, and they put a lot of time and effort into their benchmark logs on Geocaching.com. We have also heard over and over how useful geocachers’ logs have been for professional surveyors. We had built an impressive archive of historical documentation over the decades, much of which is not available elsewhere, and it is a shame to lose that.

For anyone who wants to retrieve the text (not the photos) of their benchmark logs and see others’ logs for a particular mark, you can use Internet Archive’s Wayback Machine.

The benchmarking home page (as of December 30, 2022) is available here:

https://web.archive.org/web/20221230041305/https://www.geocaching.com/mark/

The postal code search doesn’t work, but the PID search does, at least for all PIDs I have tried.

To go directly to a mark’s page, you can use URLs of the form:

https://web.archive.org/web/20221208090238/https://www.geocaching.com/mark/details.aspx?PID=[PID]

where [PID] is the mark’s PID.

Unfortunately, because I don’t see a way to view the marks a user has logged, you will need to know the PIDs of any marks you want to look up on the Wayback Machine archive.

The NGS Data Explorer (now NGS Web Map, as of November 2023) can help with that:

The NGS Map

I hope this is useful.

To anyone who enjoyed this activity, took it seriously, and understands its value, please spend some time on the NGS website and learn how to submit your data directly to them instead. Survey marks are still in constant use and your efforts will be appreciated there.

Portland—Spokane Beacon #12 in Arlington, Oregon

Sat, 03 Oct 2020 15:31:00 -0400

This is a guest post, with photos and accompanying text contributed by Dave Sbur. Thanks for your contribution, Dave!

Google Map

There was initially some confusion when trying to identify which beacon site Dave visited. We have determined that this was most likely Portland—Spokane #12 (RC2502 in the NGS database, where it is referred to only as ARLINGTON AIRPORT BEACON).

According to Arrows Across America, it appears that there were two locations for beacon #12, the first being RC2505 and the second being RC2502 (although it is not labeled as such on the Arrows Across America website, the coordinates match the site Dave photographed).

Coordinates for this beacon site are N 45.719876°, W 120.186152°.

Dave writes:

All photos were taken August 15, 2020. It’s all kind of a jewel in the rough; I was surprised to find it all in somewhat decent condition considering the age. Arlington is kind of a sleepy town, the airport is still active but is hardly used. There is a drone company that uses it for development, I understand.

If you look closely you can see some faint numbers on the roofs of the sheds for the Portland-Spokane Airway, part of the C.A.M. 32 route. No trace of a concrete arrow could be found on the site. The airport was listed in the Dept. of Commerce listings in 1931 as a DOCILF (Dept. of Commerce intermediate landing field). It was also used as an Army Air Force auxiliary field in WW2. According to the book Arlington, Child of the Columbia by Marion T. Weatherford there was a strafing range about a mile west of town the military used for practice during the war.

“Department of Commerce intermediate field, site 12, Portland-Spokane Airway. One and one-fourth miles E. Altitude, 850 feet. Irregular shape, 2,400 feet E./W., 2,000 feet NW./SE., sod, level, natural drainage; entire field available. Directional arrow marked “12 P-S.” Pole line to N., beacon tower to NW. Beacon, boundary, approach, and obstruction lights. Beacon, 24-inch rotating, with green course lights flashing characteristic “2” (.._). Aviation fuel. No other servicing facilities. Teletypewriter. Department of Commerce marker beacon, characteristic signal “H” (. . . .), operating frequencies 248 and 278 kc.”

With the above from a 1931 source, I found the discrepancies of the ‘beacon tower to NW’ when it appears to be to the SW. Perhaps things were moved sometime in the past? The altitude on the power shed is crudely painted 877′ when the listing show 850′ (current FAA listing show 890′). I found no evidence of a ‘Pole line to N’. There are various runway markers. I did not look for approach or obstruction lights evidence.

Image captions in the gallery below give more details about the various parts of the installation.

Finding RHONDA

Sun, 17 Mar 2019 09:43:00 -0400

Originally published in 2008 in Caching Now, a former publication of Berntsen International, Inc.

Shortly before the end of 2007, we began compiling yearly statistics for our benchmark recoveries. The vast majority of finds came from our far-flung adventures in Arizona and Maine. With such globetrotting tendencies leading us to some of the most scenic benchmark settings in the country, you might think that the marks closest to home (northeastern Pennsylvania) pale in comparison. That’s not really the case. Nearly all survey stations pose exciting challenges of one kind or another, especially triangulation stations! But the ones near us are easier to reach and less scenic than those we find while on vacation, and we can fit them in when we’re looking for just a quick morning hike. Honestly, sometimes we procrastinate, and we procrastinated well with LY2791.

So what was our motivation this time? We had carried that datasheet around in Rich’s car since 2003, just waiting for a day when we had nothing better to do. Why did we finally decide to search for the mark now? Becoming acquainted with Rhonda Rushing through our contributions to her book Lasting Impressions had a lot to do with it. We finally knew someone with a namesake tri-station! Of course, as president of Berntsen International, Rhonda can stamp a disk with her name any day she likes; but one in its original setting placed for a particular purpose has to be, we thought, more authentically thrilling. Perhaps she would even enjoy our report and photos so much that she might include them in Lasting Impressions, Volume II, if such a work is forthcoming? Thus finding RHONDA became our goal for the next nice autumn day.

Triangulation station RHONDA

When RHONDA was set in 1959, the surrounding area was pasture land. Ten years later, the Wemberly Hills Golf Course was established on the land just to the south of RHONDA’s knoll. It remains a popular course to this day, but our familiarity with the area, as well as prior visits to the golf course, gave us confidence that we could reach the coordinates without difficulty, and probably complete our recovery without incident.

Sunday morning was calm and the sun shone brightly—a rarity in northeastern Pennsylvania, even during the typically dry month of October. We parked in the golf course lot, then followed a dirt road toward the small knoll, a slight rise from the level of the road. Our tool bag and backpacks were bulging with the usual long measuring tape, trowels, gloves, probes, garden clippers, flagging tape, GPS and remote antenna, hatchet, folding saw, compass, and camera. I, Zhanna, carried a tripod slung across my shoulder and held the datasheet in my hand. We didn’t need a map for this excursion.

The former pasture land in the vicinity of RHONDA is now a weedy meadow, but it is still mostly open and easy enough to walk through. It is bordered on the southwest by open woods and on the north by a high stone wall. We unloaded our equipment in an area free of weeds and began to look around.

At first we saw no marks and no rock outcrops matching the description. A quick overview of the area was a complete failure, even though we felt confident in the coordinates. What did this mean? Usually it means we have some digging to do. Probing the ground near the station coordinates, we could tell that a great deal of soft but root-filled soil covered the bedrock beneath. Rich pulled back a heavy mat about four inches thick and we dug and scraped, trying to reach bedrock, but nothing revealed itself to us. Hmm…perhaps this would be a tougher recovery than we had thought. To save ourselves the sweat and frustration of digging an area too large in the wrong place, we decided to search a little harder for the reference marks, hoping that they could be found and would then lead us to the station. After all, that’s their purpose!

Eyelevel view of the disk, set into a small boulder underneath the rock wall.

Rich and I walked together in the general direction of RM1, having noted that RM2 was most likely near the thickly overgrown stone wall and would be harder to find. We descended a bit, almost imperceptibly, and spotted a large, flat outcropping slab of bedrock. Simultaneously, Rich and I saw the blue-green disk!

Using our sighting compass and the “box score” data about the reference marks from RHONDA’s NGS datasheet, we projected an imaginary line from RM1 back toward the station, and Rich paced off the approximate distance. Our long tape is usually handy in these situations, but in this case the arrangement of brush and a tree made it impossible to use. We still saw nothing promising in the vicinity of the mark. We stuck a probe in the ground anyway, to mark our guess at the station’s suspected location. From this estimated point, I used the compass again to direct Rich on the bearing which, according to the box score, should bring him to RM2. It was indeed hiding in the thicket, somewhere near the stone wall.

Zhanna points to RM 2

“Gardening”—our term for clearing back brush and weeds—was necessary. Rich hacked and slashed his way through, and eventually spotted the reference mark just a few feet from our bearing line. It was set in a rock that was halfway embedded in the ground beneath the stone wall. I fought my way through the remaining brush to stand over it, and I was able to sight a bearing line back toward the station. Rich intersected RM2 with the line we’d taken from RM1, and, combining this knowledge with that which we could deduce from the former placement of a witness post, we were able to pinpoint the station disk. We soon realized that our earlier efforts had very nearly uncovered the disk, but a thin coating of dirt had still somehow obscured it. A closer look and a quick brush with a gloved hand were all it took for RHONDA to emerge! We were thrilled to document our find with photos and to submit the first official NGS recovery of this station in over thirty years.

Now, here’s a friendly challenge: there is one more RHONDA (FM1025) to be found near Tucumcari, New Mexico. Perhaps one of our fellow benchmark hunters in the Southwest would like to attempt it?

Salt Lake—Omaha Beacon Sites #38 and #42

Jack Breeding has submitted some photos for beacon sites #38 and #42 on the Salt Lake—Omaha airway!

Beacon SL-O #38

Arrow at SL-O #38 site

Jack writes: “Just a few dozen miles to the west of SLO42 and the very first beacon arrow I ever saw in person. This picture and my visit were made in 2015. As you can see, it looks like someone ‘salted’ the ground around the arrowhead - nothing grows there. Made me wonder if some Beacon-keeper had trouble with weeds overgrowing the marker and decided to do something about it! This one is easily visible on Google Earth.”

Dave Izatt has submitted the following photos of LP0496 - SAN FRANCIS SALT LK AWY BN 57. The tower is gone, but the arrow is intact. Dave says that a 4-wheel drive vehicle with high clearance is required to drive directly to the arrow.

The beacon tower’s description is difficult to find now, because it has been marked as Destroyed in the NGS database. Below is the original Coast & Geodetic Survey description written upon their observation of the site in 1940. Strangely, they claim “There is no concrete arrow to indicate the course.” Is this a mistake in the description? I can’t imagine the arrow having been added after 1940. Also of interest is that (according to Wikipedia) Low is a ghost town, abandoned in 1955 due to lack of local water.

GPS on Bench Marks—Volunteer Opportunity!

Tue, 20 Mar 2018 20:02:00 -0400

Fellow survey mark hunters, please consider helping NGS with this year’s GPS on Bench Marks initiative. Data submitted by August 31, 2018 will help in the development of the new geoid, GEOID18!

All observations are welcome. If you don’t have professional surveying equipment, no problem—please submit your observations, including field notes and photographs, to assist those who have pro equipment in finding the mark!

And don’t forget, even with consumer-grade GPS equipment such as a handheld unit or phone, you can always update the coordinates for marks with SCALED positions.

To help focus efforts, NGS publishes a map of prioritized marks. These are selected marks that, if found and if observations are submitted, will help improve the new geoid. The list of prioritized marks is also available in Excel and other formats.

1932 Newspaper Article: New Beacon on Red Butte Mountain near Salt Lake City, UT

Thu, 08 Feb 2018 17:54:00 -0500

Website contributor Dave DuPree has found the following image and article in The Salt Lake Tribune from Saturday, November 26, 1932 (page 33). This is the article to which Dave referred in his comment on the Needle Peak video. Thanks, Dave!

Image caption:

Man’s ancient beast of burden, the mule, has been having a busy week aiding in the construction of a beacon to make the most modern way of travel safer. Above is a Fort Douglas soldier leading a mule up Red Butte mountain bearing equipment for the airplane beacon on the mountain top. The other view shows Lieutenant Howard H. Reed directing the placing of the tower.

Full article:

Primitive Transportation Aids in Replacing Beacon

Primitive methods of transportation have been used during the past week to make safer the most modern means of travel. The lowly mule, used as a beast of burden since earliest times, has been kept busy so that the path of airplanes traveling across the continent may be made easier.

With the adoption of the recent policy of the airways division of the United States department of commerce to replace beacon lights with equipment of more efficiency, Red Butte mountain for the past few days has been the scene of much mule travel. The animals loaned the division by the commanding officer at Fort Douglas have been employed to carry the new beacon to the mountain top, where it will replace the present one as a guide to pilots coming into Salt Lake valley from the east.

W. E. Kline, in charge of the airways division office, has had charge of the work, which is expected to be completed Saturday or Monday. According to Mr. Kline, the new 36-inch beacon light will have a beam of 1,500,000 candlepower, or from 300,000 to 400,000 greater candlepower than the light now in use. He said the present construction is part of a plan to replace more important beacons with equipment of greater efficiency.

Art Young of the Ardiente Community Hiking Enthusiasts (ACHE) has submitted these photographs of the arrow associated with Los Angeles—Salt Lake Airway Beacon 31A (NGS PID GR1900). The arrow, which is referred to in the linked survey datasheet, is about 700 feet east of the former beacon site (coordinates for the arrow are N 36.685350°, W 114.517609°). The arrow has been painted orange since the images in Google’s satellite view were captured. It appears to be in excellent condition.

Art also noted that the Old Spanish Trail passes just a few hundred yards to the southwest of the arrow. The route of the Old Spanish Trail is mapped here: ArcGIS Old Spanish Trail Map.

Harold Nelson of MaineDOT has sent along old horizontal control datasheets from Hancock County, Maine. These were developed when the Coast & Geodetic Survey (now the NGS) was a component of the ESSA, Environmental Sciences Services Administration. The ESSA was reorganized into NOAA in 1970.

View and download sheets

These sheets are reminiscent of the USGS datasheets, which still exist only in a similar paper format. Note there are only designations, no PIDs—PIDs were not assigned until the NGS database was created and marks were entered. Some of these datasheets contain sketches that do not exist in the online NGS database! (If you’ve ever seen a recovery note that referred to a sketch or drawing, and wondered where it was—well, it was on sheets like these.)

7 Myths About the Lighted Airways

Sun, 05 Feb 2017 11:50:00 -0500

Often-repeated misconceptions and historical fallacies regarding airway beacons and concrete directional arrows

Written by David M. DuPree

1. MYTH: The airway beacons were dismantled when the U.S. entered WWII to prevent enemy forces from using them for navigation.

As America began preparing for war in the late 1930s, the number of airway beacons continued to increase, peaking at the end of 1941 and remaining relatively constant from year to year for the duration. From 1939 through 1941, 357 rotating airway beacons were added to the nation’s lighted airways. Amber Civil Airway No. 8, extending along the California coastal region from Los Angeles to San Francisco, was built during 1941 and continued operating through the war years. Aside from infrequent, localized and brief blackouts, the lighted airways – even the coastal routes – remained operational as a wartime necessity. During blackout exercises, airway beacons were specifically exempt. It wasn’t until the postwar period that the number of beacons returned to the 1937-1938 levels. Between 1940 and 1945, there were more airway beacons operating in the U.S. than at any other time in history.

2. MYTH: The airway beacon towers were scrapped during WWII because the steel was needed for the war effort.

The airway beacons were an essential part of the war effort. Many new beacons were added to the system beginning in the late 1930s (see above). WWII resulted in an immediate and massive increase in air traffic from coast to coast. This included unprecedented levels of military flight training, as well as the movement of personnel and materiel on a grand scale. The light beacons remained indispensible for night navigation throughout the war.

3. MYTH: The large directional arrows were the first navigation aids on the airways and the beacons were added later.

Rotating beacons were in use on the airways as early as 1923. Directional arrows were not introduced until late 1926 or early 1927. Concrete arrows were built only as daytime visual aids to supplement the rotating airway beacons and other site markings.

4. MYTH: Large directional arrows were built and used by the U. S. Air Mail Service.

I have found no evidence that the Post Office Department (U. S. Air Mail Service) ever built or utilized directional arrows on its airways (1918-1926). There is no known record or documented instance of an Air Mail Service pilot relying on large directional arrows for course information. The first concrete directional arrows were built after the Department of Commerce assumed responsibility for the development, construction and maintenance of the federal airways in late 1926. Though used by contract air mail operators, the arrows were not established by the U. S. Air Mail Service.

5. MYTH: Concrete directional arrows were located at all federal airway beacon sites.

Concrete directional arrows were included in construction specifications for airway beacon sites only from 1927 to 1932. However, even during that period not all beacon sites included concrete arrows. In fact, there were entire airways from that period that were not equipped with arrows. For instance, some coastal routes didn’t need large directional arrows for daytime navigation since they were already equipped with the ultimate visual marker – the coastline. As with most aspects of configuring and equipping airways and individual beacon sites, the airway engineers determined whether arrows were needed. In any case, you are unlikely to find a concrete arrow at an airway beacon site built after 1932. Fewer than half of all airway beacon sites included a concrete arrow.

6. MYTH: The concrete directional arrows were illuminated at night.

As originally envisioned by the Department of Commerce in 1927, the concrete arrows were to be illuminated by lights mounted overhead on the beacon towers. This was implemented at some sites during 1927, but it was soon determined to be impractical due to several factors. Among other things, the spotlighting was inadequate for making the arrows distinguishable at night, and at remote locations, the limited wattage provided by the on-site generators was increasingly needed for other things, including the newly introduced course lights. The arrows remained in the plans, but they became directional aids for day, visual conditions only.

7. MYTH: The airway beacons were in service for only a few years.

Airway beacons were operated continuously on the federal airways from 1923 until the mid-1960s, a period spanning more than four decades. The decommissioning of airway beacons was a gradual process that began in the 1950s. The final large-scale decommissioning occurred in the mid-1960s. The rotating beacons guided the early Air Mail’s open-cockpit biplanes, the classic planes of the Golden Age, the American air armada of WWII and the majestic postwar prop airliners. The big lights continued serving well into the jet age. A few beacons continued to operate into the 1970s and beyond. The State of Montana still operates several airway beacons, while a few more around the country have been maintained as hazard/landmark beacons. Upon retirement from airway service, hundreds of surplus beacons and towers went to work at airports, where they continued to serve as navigation aids. Refurbished and sometimes updated with high-tech lamps, some of these beacons (and towers) have been operating for more than 80 years!

Harvey's Counterfeit Beacon

Mon, 30 Jan 2017 09:21:00 -0500

by Harvey Hartman

When I first started erecting my vintage airway beacon tower, I was unaware of its historical significance. I simply wanted this cool old beacon for our airport. Therefore, an exact restoration wasn’t in my original plans. While I DID erect the tower close to its original condition, I took a few liberties to upgrade it in a few structural areas and improve its beacon and electrical system. The control system (still in progress) is being brought up to modern standards and will include a receiver that will allow a pilot to activate the beacon from his/her cockpit prior to landing. (i.e. PCL, or “Pilot-Controlled Lighting” in FAA terminology.)

The Original Vintage Beacon

Crouse-Hinds model DCB-36

The beacon that came with my tower was a 36″ diameter Crouse-Hinds model DCB-36, was double-sided with two very-expensive Fresnel glass lens sets, and was equipped with two 1,200,000cp (that’s 1.2 MILLION candlepower!) bulbs. (One was the in-service bulb and the other bulb was a backup mounted in an automatic bulb-changing mechanism.) Introduced in 1932, this model quickly became the standard beacon for the Federal Transcontinental Lighted Airway System. It also eventually replaced most, if not all, of the earlier beacons as normal wear and tear, as well as storms and vandals, took their toll. (The big DCB-36 is also noteworthy in that it was chosen by the Lighthouse Division of the Department of Commerce in 1936 to upgrade its coastal lighthouses from carbon arc, and acetylene-powered beacons.) However, the venerable DCB-36 design is now 85+ years old and replacement parts are getting hard to find. And those parts that ARE still available are getting very expensive. Therefore, I made the disappointing decision to not reinstall the historic original beacon. Instead, I built a stand-in (a stinkin’ counterfeit, if you will) beacon to put on the tower and the original beacon will be restored and displayed inside my hangar where it’ll be safe.

Building My “Counterfeit” Beacon

Due to my decision to not reinstall the original beacon, I set out to find a replacement beacon. I quickly discovered that new (or even USED) beacons aren’t cheap!!! Not one willing to forfeit quality and style for an affordable price, I elected to design and build my own; a substitute with two priorities in mind. The substitute had to be robust and cheap to maintain/repair, and it must look like something out of the late 1920s – early 30s.

With the tower being a late-1920s model, I decided to model my homemade beacon after the earlier “double-drummed” beacons. (“Double-drum” is slang for beacons that use individual housings, or “drums”, mounted back-to-back to produce the alternating white and green flashes signifying the location of a civilian flying field. The later “Single-drum” beacons such as the DCB-36 used one housing that contained a single bulb in the center with a green lens on one side of the housing and a clear lens on the opposite side to produce the two flashes.

I decided to model my “counterfeit” beacon after the 24″ double-drummed design. However, my fondness for old steam locomotive headlights and America’s glorious 1920-30s Art Deco period may have also influenced my new beacon’s design.

And while it will be virtually impossible to stop the storms and vandals, at least I can make their damage less expensive. Therefore, my stand-in beacon uses common yard floodlights instead of the exorbitantly-expensive high-powered metal-halide bulbs and Fresnel lenses, and its housing is constructed of thick steel instead of cast aluminum like the original. Unfortunately, it was beyond my capabilities to construct a replacement for the original rotator base so I’m reusing it for the time being, but with a steel shield added around it for increased protection.

My new beacon had a humble beginning as an old propane tank which donated its heavy steel end domes to become my new beacon’s backshells.

I then built their mounting yokes and an adapter box that would mate the beacon to the rotator’s output turntable. This completed the basic beacon and its mount.

The Ring Shields were fabricated next and the visors followed. And this was the end result.

A trip to the powdercoaters resulted in this sexy thing! Gratings were fabricated and were added in front of the bulbs to prevent birds from attempting to build nests during the day when the beacon is stationary. From ground level, these “platinum silver” grates look like fluted glass lenses.

The beacons’ elevation angles can be adjusted using this simple jack screw device between 0 degrees (on the horizon) to +20 degrees above the horizon.

We hoisted the “counterfeit” beacon to the top of the tower on 9 April 2016.

And IT WORKS!

Note: The bright white “dot” centered under the beacon in the video is a floodlight that illuminates the windsock when the beacon is operating.

That's Harvey in the white hardhat

That’s where my “counterfeit” beacon and its tower are as of January 2017. I still have to design and build the PCL system but as the video showed, the beacon can be operated manually for demo purposes.

October 2017 Update

2 x DCB-24 = DCB-224

I have recently located and purchased an original late-1920s “double-drummed” Crouse-Hinds DCB-224 airway beacon to replace my “counterfeit” beacon.

I suspect that your first question is probably wondering why I’m replacing the homemade beacon that I spent so much time and effort building to replace my big DCB-36? The simple answer is because it’s not original. It’s incorrect for me to call my beacon tower project a 1920’s Airway Beacon when the beacon itself is a 2016 product. “BUT, (someone is bound to point out) the reason for not reinstalling the DCB-36 was to avoid exposing an historical artifact to potential damage. How is putting up a different antique beacon going to change that?” My reasoning is that while it would be virtually impossible for me to prevent such damage, at least I can make that damage less expensive to repair. I accomplished this by designing my homemade beacon to use common PAR38 landscaping floodlights with their built-in lenses and reflectors, instead of the original beacon’s hugely-expensive Fresnel lenses, and special bulbs. While the large, double-sided design of the 36” diameter DCB-36 would be difficult to modify, the twin single-sided DCB-24s can successfully use the same PAR38 bulb system as my homemade beacon. This will allow me to say that both my tower and its beacon are alumni of the old Federal Transcontinental Lighted Airway System.

So what’s going to happen to my homemade beacon? Of course, it’ll still serve duty on my tower until the rebuilt DCB-224 beacon is ready to replace it. However, my ultimate plan has always been to have an operational beacon on my tower AND a backup beacon in reserve that would replace the in-service beacon when it needed major repairs that would likely render our airport’s beacon out of service for an extended time. My homemade beacon will serve that purpose well.

For the purists out there, please note that my “PAR38 modifications” are not permanent (i.e. the drums are not drilled, cut, or otherwise irreversibly altered); therefore, the drums can easily be returned to original condition someday. (Unfortunately, the same cannot be said for the propane tank used to create my “counterfeit” beacon.)

The Story Behind Our “New” Beacon Tower

Sun, 29 Jan 2017 13:17:00 -0500

by Harvey Hartman

Restored beacon tower

Located at the southern edge of a residential airport on the west side of Houston stands a 42ft tower that is nearing the end of a long relocation and restoration effort. This tower is one of the last few survivors of the 1920s Federal Lighted Airway Beacon System.

Following the completion of the Transcontinental Railroad in 1869, coast-to-coast postal mail was carried by the railroads. While this was a tremendous improvement over the prior carriage by overland stagecoach or by steamship through the Isthmus of Panama, it still required extensive handling of the mail, and its resultant delays, as it was transferred between railroads over the length of the five-day trip.

In 1916, Congress authorized funds for the Post Office Department to begin experimenting with using aircraft for quickly moving high-priority mail long distances and in 1918, additional funds were appropriated to establish experimental airmail routes. For nighttime navigation assistance over these experimental routes, bonfires were spaced at 10 mile intervals and flights through the night became a simple matter of “connecting the dots.”

In 1923, the Post Office began constructing a permanent New York-to-San Francisco transcontinental airway. This airway was initially lighted between Chicago, IL and Cheyenne, WY using a system of steel towers equipped with rotating electric beacons. (The reasoning behind lighting only the middle third of this coast-to-coast airway was that planes departing in daylight from either end would plan to arrive at the lighted portion before nightfall. They would then navigate through the night using the lighted beacon towers until dawn again, and they would continue the final third of their trip in daylight.)

Standard DoC installation

On 1 July 1924, postal authorities began regular around-the-clock operations (establishing the first scheduled air operations in the US). Responsibility of the airway was transferred from the Post Office to the new US Department of Commerce Airways Division upon its creation in 1926 and the construction of additional lighted airways soon followed. A southern east-west transcontinental airway was completed between Los Angeles, CA and Atlanta, GA in 1931 and this route passed through Dallas, TX. Dallas was then connected to Houston by a short north-south airway, then Houston-to-San Antonio, Houston-to-Austin, Houston-to-New Orleans, etc. By 1933, more than 18,000 miles of federal airways were marked by 1,550 beacons spaced at 10 to 15 mile intervals across the US.

Following WWII, the rapid advancement and availability of in-cockpit electronic navigation equipment made the old lighted beacon system obsolete and it was decommissioned and dismantled in the late 1950s and early 60s. The beacons and their towers were then donated to municipal airports for use as airport beacons—one apparently ending up at the La Porte Municipal Airport on the southeast side of Houston.

In 2004, the city of La Porte received a federal grant to modernize its airport lighting facilities and this included replacing its old rotating beacon and tower with a modern version. At that time, our own decrepit and failing beacon was already deep into borrowed time and wasn’t worth repairing any more. A deal was made and the La Porte tower and its beacon were dismantled and moved to our airport.

IDECO Builders Plate

La Porte’s steel beacon tower was built by IDECO (the International Derrick & Equipment Company, one of the major suppliers of towers for the Federal Lighted Airway Beacon System) during the late 1920s. For being 85+ years old, the old tower was still in very good condition, owing much of its long life to the six to eight coats of thick paint on top of a galvanized undercoat. Nonetheless, the tower was thoroughly sandblasted, inspected, rebuilt piece by piece, and repainted in Aviation Orange and Aviation White colors.

The beacon assembly that came with the tower was a 1938-40 Crouse-Hinds model DCB-36 (built specifically for the Civil Aeronautics Authority) with a 12rpm rotator mechanism. The beacon was still operational but due to the scarcity of replacement parts, that beacon has been retired and a replacement (“counterfeit”) beacon has been fabricated. The La Porte beacon, as well as our original beacon, were controlled by simple photocell switches and they operated all night, every night. However, our new beacon will be pilot-controlled (via microphone “clicks”) in order to limit its operational time, thus reducing its maintenance and electricity costs.

Its fresh coat of paint belies our “new” beacon tower’s long history of guiding pilots through the night skies. The construction of the Federal Lighted Airway Beacon System in the 1920s and ‘30s enabled scheduled around-the-clock flying for the fledgling U.S. Airmail Service and is regarded as the birth of commercial aviation in the U.S. Of the original 1550 towers, only a few dozen are known to exist and of those, only a small few have been restored.

Our tower is one of those few!

Emergency landing field sign

Trivia: During the early years of the Federal Lighted Airway System, government specifications called for the construction of emergency landing fields (often not much more than cleared fields leased from area farmers) co-located with every 4th beacon site along the airways. In addition to their white rotating beacons, the towers were also equipped with fixed (non-rotating) 18” diameter course lights that shone up and down their airways towards the previous and next beacon sites and visually defined the airways. When no emergency landing field was nearby, the course lights were red. However, if a beacon site included a co-located landing field, the course lights were green. This is why civil land airport beacons are green and white to this day.

The Information Literacy of Survey Mark Hunting: A Dialogue

Wed, 09 Nov 2016 09:07:28 -0500

At long last, we’ve been published!

Over the past year, my colleague Donna Witek and I have been writing an article about the application of survey mark hunting as a recreational activity to the new Framework for Information Literacy. In November the article was published in In the Library With the Lead Pipe, an open access, open peer reviewed journal. The writing and editing process (specifically the open peer review process) was a great experience for both of us. And the conversations we had with our two reviewers were invaluable in shaping the piece into what we think is fun and compelling reading—rather on the light side for an academic work.

Gaps on the Map: Pueblo, Colorado to Cheyenne, Wyoming Beacons

1930 Pueblo—Cheyenne: Excerpt of a beautiful hand-drawn map

I received the following fascinating information from website contributor Jeff Johnson. He has used two airway maps to estimate the positions of beacons that don’t appear in the NGS database, and therefore for which we have no location data.

I’ve added the actual coordinates as indicated on the NGS datasheets where they exist. I also found two arrows thanks to Jeff’s work—can you find more? Leave a comment if so!

In addition to Jeff’s description, below, of his method and results, I’ll include his insightful comment:

What fascinates me most about these beacons is that you and others seem to be inferring their positions from secondary data: that if there ever was an exhaustive and official book or list published by the airmail service, it is either lost, or waiting to be discovered in some library basement. That a nationwide system could be implemented, and then more or less lost, within a few decades, along with any documentation that might have once existed, is fascinating.

Jeff searched the Coast Survey’s Historical Map & Chart Collection using their “classic” search: Office of Coast Survey Historical Map & Chart Image Catalog

The chart Jeff used to develop the table below is listed as chart #131, Airway Map Pueblo Colorado to Cheyenne Wyoming, 1930.

Subsequently he found another version of the map from 1928. (The 1930 version is available at the Library of Congress and is included in my index to their airway map collection, but the 1928 map is not.)

Jeff writes:

This one chart shows some 30 beacons in eastern Colorado and southern Wyoming, only 11 of which seem to correlate with your lists of PID numbers. I decided to attempt a spreadsheet of latitudes and longitudes by measuring on-screen pixel distances to the parallels and meridians shown on the chart, and interpolating.

The beacons numbered 0? to 20 run south-to-north on a line that roughly matches today’s Interstate 25. Beacons 37 to 44 run west-to-east across southern Wyoming. I actually think that, given the large scale of the chart, my interpolation method should fix coordinates to an accuracy much better than 500 meters, perhaps 50 or less. But when I compare my values against those from your PID tables, where they exist, they aren’t quite that good. One possibility is that latitude and longitude were referenced to a slightly different global datum than that used by today’s GPS. Another is that the charts, although superbly drawn, are nevertheless hand-drawn. This is evident when they are compared to charts published just a few years later.

There is the odd case of beacon #6 near Monument CO: I’m sure your PID file has it located properly, because although the arrow is long gone, there is a long area of concrete rubble visible from satellite. Also, the fact that the road that runs next to this is apparently still known as Beacon Light Road is definitely a clue. But the position of #6 on the 1928-30 charts is several Km off. I can only conclude this is a charting error. How it wasn’t discovered in the two years between is odd though. Both charts are marked “Advance Sheet — Subject to Correction.”

Beacon #8, near Castle Rock CO, seems needlessly mysterious. The 1928 chart shows it, but it’s not on the 1930 chart. Instead, the 1930 chart shows two others, labeled 8A and 8B. All three are in a tight little bunch. It’s like someone kept tweaking the location: “No, I think it should be a little more to the left.” I wonder what might have been going on.

The I-25 corridor is considerably more built-up today, and most of the sites in my table seem to be under modern concrete or structures. I’ve never done any field work on this remarkable little side bar of 20th century archaeology: only looking at satellite views, and I’m probably not the best at interpreting these.

This is all from just one chart. I hope you or someone else may find this archive of aeronautical charts a useful additional source of candidate sites for exploration (if you weren’t already aware of its existence). It does, however, demand some time and effort to do the pixel-counting and interpolation of coordinates.

I’m just fascinated by the interactive map on your web page: not so much the lines of dots, but the gaps in the lines of dots.

Beacon Tower Near Polkinghorne Spring, Nevada

Sun, 03 Jul 2016 08:39:28 -0400

Jack Fawcett visited this tower near Polkinghorne Spring, Nevada on June 2, 2016. The tower was nearly intact, except for the glass lens (pieces of which he found at the site) and the carbide tanks. There is 4WD vehicle access to within one mile of the tower; from there, a hike up the hill is required. A geocache is hidden at the site as well.

According to website contributor Harvey Hartman, this tower is of the style produced by IDECO (the International Derrick & Equipment Company), as shown in the 1928 brochure IDECO Airway and Airport Beacon Towers.

Approximate coordinates of the tower are N40.228794°, W117.741353°.

Beacons 62 and 64 in Eastern PA

Sun, 26 Jun 2016 14:12:28 -0400

Bob Pastore submitted the following evidence of what remains of Beacon 62 in Summit Hill, Pennsylvania (approximate coordinates: N40.819438°, W75.874985°). He writes:

62 is just south of Summit Hill, PA—a little town that the star on the chart is just touching. 64 is on Blue Mountain on the Lehigh Water Gap near Palmerton, PA. It appears as this is a CLE — NY or ORD — NY route.

As a retired airline pilot I recall flying these routes using modern navigation aids and they went right over Summit Hill and Palmerton.

If you look at the chart, note that there is an airway which comes out of Allentown VOR (the 291 degree radial noted on the chart), a modern day navigation aid put in place in the late 40s. They too are almost obsolete what with GPS. The airway is from the Milford, PA area and note that it is just below the arrows of the beacon airway. Not too far off as this was the principal route from CLE, DTW, ORD to NYC.

Airway Beacon 10 near East Hampton, Connecticut

Sun, 05 Jun 2016 20:25:28 -0400

Michael LaRose has submitted the following photos from the former site of Beacon 10 on the New York—Boston airway (NGS PID LX4898).

Michael writes:

[The site] lies next to a modern commercial communication tower right next to a condo complex. I also found another USGS marker nearby which I presume was placed to replace the tower upon its demolition. The concrete pad is really the only evidence left and I walked right past it at first because it is quite overgrown. There is a well right next to the pad but appears to predate the beacon based on its construction.

I think the well is the one referred to in the datasheet description for BAKER, the triangulation station at the site. (The marker he found is BAKER RM 2.)

Beacon Near Plainfield, Illinois

Sun, 10 Apr 2016 11:31:28 -0400

Roger Helm has submitted the following photos and information about a beacon north of Plainfield, Illinois.

There is a beacon that was north of Plainfield, Illinois, that was saved in 2014 and moved about four miles by the Plainfield Historical Society to the Railroad Museum located on Illinois Route 126 near the Du Page River and the CN rail line (formally the E,J, & E). It was located on Book Road, between 119th street and 127th Street (coordinates: N 41.659808° W 88.184783°).

The beacon's original location, in happier days

Interestingly, Google’s Street View from 2012 shows the beacon in its old location, while the satellite view (no date given, but obviously newer) shows the beacon at the rail museum (coordinates: N 41.609017°, W 88.211445°).

The beacon may have been No. 37 as shown on this map: Air Navigation Map No. 9; Chicago, Ill. to Iowa City, Iowa; 1929/1933

… or No. 25 as shown on this map: Airway Map No. 111; Chicago Ill. to Milwaukee Wis.; 1930

… or something else entirely. Please comment if you have any thoughts!

Portland—Spokane Beacon 3 A: A Personal Connection

Thu, 31 Mar 2016 21:59:28 -0400

Ray Hays has submitted the following photo of his uncle, Victor Hays (born 1909), with Beacon 3 A along the Portland—Spokane Route (see below for the text of the datasheet, which is now inaccessible via direct link because the mark is considered Destroyed).

This beacon sat atop Beacon Rock in what is now Beacon Rock State Park, along the Columbia River. Beacon Rock is a prominent basalt plug rising to an elevation of nearly 850 feet. A trail of boardwalks and switchbacks provides hikers a path to the summit.

Victor Hays on Beacon Rock

Not much is known about the photo, but Ray suspects that it was taken before World War II. It is the only photo of the beacon that exists in the state park’s archives. I was unable to find any other images of the beacon online.

Beacon Rock has an interesting history. Surprisingly (or at least I was surprised by the coincidence!), it was named Beacon Rock long before the airway beacon was placed there. In fact, it was originally designated Beacon Rock by Lewis and Clark in 1806. By some point in the 1800s—sources vary on the date—the feature was more commonly known as Castle Rock. Then in 1915, the feature’s name was officially changed back to Beacon Rock by the USGS Board on Geographic Names.

The airway beacon was in place at least as early as 1931, as it appears on an airway map from 1931. (It can also be seen on the maps from 1933 and 1934).

The beacon was first observed as an intersection station by the Coast & Geodetic Survey in 1938. And it was destroyed before 2004, as reported by Geocachers and the U.S. Power Squadron. Ray Hays’ friend Ken Cole remembers the beacon up on the rock and thinks it blew over in a bad wind storm in the 1950s. He is quite sure it was before the Columbus Day storm of 1962.

Beacon Light Purchased—Can Anyone Help Identify It?

Wed, 30 Mar 2016 20:42:28 -0400

Recently I was contacted by a man who has purchased an old airway beacon light. He is wondering if anyone can provide details about it, or some tips on how he might go about finding more information about it.

The plate on the base is illegible. Lettering on the drum says “Department of Commerce.” That’s all the information he has at this time. He has no idea how to go about determining where it came from, nor do I. Can anyone help?

NGS Historical Geodetic Control Diagrams Available

Mon, 21 Mar 2016 22:30:28 -0400

For years, NGS hosted its digital map collection on an FTP site. It was a treasure trove of historical geodetic maps and indexes. In January I realized that the link I had posted from my site to the NGS FTP site no longer worked; communications with NGS indicated that the FTP site is down indefinitely while they work to hire a web developer and content manager, who will then reorganize the site and make the historical content available once more. Maybe. Maybe within the next few decades. (No offense to NGS, but I know firsthand how historical digitization projects are a low priority for many organizations.)

In the meantime, I have posted the files here: NGS Historical Geodetic Control Diagrams

My sincere appreciation goes to David Grosh at NGS, who downloaded, prepared and sent the files to me.

New Orleans to Atlanta Beacon 2

Thu, 04 Feb 2016 21:49:28 -0500

These images were submitted by Reese Patterson, who found them in the Fort Pike State Park collection at the Louisiana State Archives. He used the beacon photos from the 1940s in conjunction with Google Satellite imagery to pinpoint the location of the beacon foundation at N 30.166530° W 89.737625°.

Interestingly, the beacon’s foundation also serves as the setting for a reference mark disk, PIKE RM 3 (NGS PID BH1160). According to the reference mark’s datasheet, the beacon’s designation was NEW ORLEANS—ATLANTA AIRWAY BEACON NO. 2. It was still standing in 1954, but by 1963 it had been destroyed. The page for this reference mark on Geocaching.com (BH1160) shows close-up photos of the disk, although as of this date, no geocachers’ photographs show much of the area surrounding the platform.

The final three images in the gallery were taken after the beacon’s removal, but they show the area in fine detail.

Beacon Light—Information Wanted

Wed, 25 Mar 2015 14:02:28 -0400

The following photos were submitted by Bill Huber. He has obtained the beacon light from LOS ANGELES DENVER AWY BCN 76A (NGS PID KL0666), a tower in Eagle, Colorado, and would like to know more about it. Bill writes:

I have the Beacon AWY 76A KL0666 of the NGS data sheet. It was in Eagle, Colorado at a elevation of 10,485. the rotating beacon was made by Carouse-Hinds with a serial #135. The two stationary beacons were made by Carlisle Finch with serial #11757. It was removed off the tower by the company I work for about 25 years ago and stored. I would like to get as much info as I can on this beacon.

Photos of the beacon light in its current condition are below (click thumbnails for full-resolution images). Can anyone offer more information?

Where Was Beacon 52?

Sat, 07 Feb 2015 09:08:28 -0500

Richmond—Washington Beacon 52

by Stephen Bennett

The problem

A portion of a 1948 USGS topgraphic map of Nanjemoy, MD quad

The lat/lon position given by the NGS data sheet^[1] for Richmond—Washington Airway Beacon 52 does not match the description given. Why? I did some research and these are my findings. So where was it actually located?

First possible answer

Air Navigation Map No. 59, Washington, D.C. to Savannah, Ga., 1936

The NGS data sheet^[1] says Richmond—Washington Beacon 52 was located at POSITION - 38 19 33.47086(N) 077 10 38.12877(W). This is the present day location of Caledon State Park in King George County, Virginia.

A 1948 USGS topo map titled “Nanjemoy”^[2] seems to agree with the coordinates given by the NGS data sheet, but it only shows “Airway Beacon”. It does not specify Beacon 52.

But wait. Something isn’t right! The description given in the NGS data sheet describes the location as follows:

"IT IS ON THE TIP OF A POINT OF LAND, ON THE W BANK OF THE POTOMAC RIVER, ABOUT 3.5 MILES E OF THE SMALL VILLAGE OF BROOKE."

The description given of the location by NGS does not match the coordinates given. The coordinates given by the NGS data sheet are not on the tip of a point of land, and they are not 3.5 miles east of Brooke. The given coordinates are nearly 12 miles southeast of Brooke.

Second possible answer

An aeronautical strip map^[3] of the Richmond to Washington route shows beacon 52 (as described by the NGS) on a point of land 3.5 miles east of Brooke. This point of land is called Brent Point and is mostly owned by Widewater State Park. Dominion Power had planned to put a power plant there but instead sold it to the state to become Widewater park.

This location for beacon 52 is also corroborated by an air navigation map of the route from Washington to Savannah^[4].

Interesting 1952 imagery

I attempted to use aerial imagery to prove or disprove one location vs. the other. The only imagery-related evidence I found that may cause me to lean one way or the other was this 1952 aerial photo of Brent Point. It’s not a smoking gun by any means—more like a grainy Bigfoot photo. What do you think? Could this be it? The area appears to have been fenced off. Could a tax map of Stafford County shed some light on past ownership of the small parcel?

The red lines in the second image are Google Earth’s measuring tool which indicated 50 feet. (Each red line is 50 feet long.) Could one of these two long narrow objects be a concrete arrow? They both appear to have points but in opposite directions.

Summary

Beacons along airway

Which was correct? The NGS coordinates or the NGS description? In this writer’s opinion there is strong evidence (though not conclusive) to suggest that beacon 52 was located at Brent Point (the location shown in the air charts^[3,4] and as described in the NGS data sheet^[1]) and not at the coordinates given in the NGS data sheet. I come to this conclusion for the following reasons:

Brent Point is a much better match of the NGS description of the location being 3.5 miles E of Brooke and on a point of land.
Taking into consideration the path along the beacons, beacon 52 is a better fit at Brent Point than at the NGS coordinates.

Existing Airway Beacons

Thu, 21 Nov 2013 18:12:28 -0500

Here are some photos of existing airway beacons, contributed by Dick Merrill.

Leadville, CO airport/airway beacon

The Leadville beacon is on the grounds of the Leadville airport and was probably part of the airway beacon system. It is identical to an airway beacon except for the green lens. (Airway beacons were white on both sides while airport beacons are white and green.)

Longview, TX airway beacon

The Longview beacon is in the yard of a farm off of Highway 59 just north of Longview, Texas. The light is gone, but the tower is all intact.

Beacon 23 near Kingsport, TN

The last photo is of Beacon 23 near Kingsport, Tennessee on Chimney Top Mountain. It can be seen from I-81 but it is not obvious; binoculars help.

Airway Beacon near Delta, UT

Tue, 12 Nov 2013 21:01:28 -0500

The photographs of this beacon site were contributed by Dean Draper. The site is located in Millard County, Utah, about 20 miles southwest of Delta. Also in the same location is the NGS triangulation station BEAK (KO0428).

Please leave a comment if you have more information about this beacon, perhaps its number or any details of its history.

A USGS topo map of the area shows the triangulation station, but no beacon. Could the designation BEAK derive from the word “beacon”?

Kentucky Airway Beacon 70 in Warren County, KY

Beacon 70

by Dick Merrill

View/download report in pdf format

On October 26, 2013 I visited the Bowling Green, KY area in an attempt to document the location, and any remaining evidence of Airway Beacon 70; beacon 70 was a lighted beacon on the Dallas to Cincinnati airway. While in the area, I also explored the remains of the Bowling Green AN radio range. The excerpt below from the 1945 Nashville sectional aeronautical chart shows the Bowling Green radio range located about 5 miles southeast of the Bowling Green airport. Beacon 70 is about 10 miles east of the airport, just inside the magenta 10 mile radius ring, surrounding the airport. Airway beacons are shown on charts as a star with two arrows pointing to the next beacon on the airway. Beacon 70 is also west of the Barren River, off of S. Ben Thomas Road. (See Topo map below)

The Beacon 70 site was located using a handheld Garmin 496 GPS receiver and was found at the coordinates shown on the NGS data sheet shown below. The coordinates are 36 56 01.80065(N) and 086 15 32.88192(W). The beacon tower is gone but a concrete slab remains within a small grove of trees. The tower leg locations can be seen but only a small portion of the legs remain as they were cut off close to the slab during abandonment operations. The tower orientation was determined by sighting along the southerly tower leg stubs and was found to be running in a southeast-northwest direction at about 120 - 300 degrees.

Clump of trees in the left background may have been the location of a generator shack if one was installed. Since the site was adjacent to a county road power was likely from a commercial line.

I did not find any trace of the northeast tower stub, but it may have been covered by plant debris or it is possible the slab was poured after tower construction and the missing stub is not covered by the slab. I hope to return to this site soon and clean off the slab and try to find the northeast stub and study any other artifacts present.

Airway Beacon 25 near Johnson City, TN

Beacon 25

by Dick Merrill

View/download report in pdf format

For several months I have been looking for the location of Tennessee Beacon 25, a lighted airway beacon on the Washington D.C.-Memphis route. I had coordinates taken from the 1945 Winston-Salem sectional chart so the location was approximately within a one square mile area. Examination of topo. maps and aerial photos didn’t help and for a while I was afraid the beacon may have been destroyed during the building of the nearby I-81.

Tennessee has a very good online GIS system of land ownership. I looked for a farm that might have been around when the Beacon was active. The first land parcel I selected was a hit. I called the number for the Osborne family near Blountville, which is south of Bristol and talked to Mrs. Osborne. She knew exactly what I was interested in and when I explained my quest she stopped me and said, "Oh yes that is the light that used to be on the hill behind my sister’s house." I asked if I could come by sometime and look for evidence of its location. She agreed and said stop by anytime.

A portion of the 1945 Winston-Salem sectional chart showing the location of Beacon 25 north of the Tri-city airport.

I was in Bristol late in November of 2012 and called her to arrange a visit. She said she would be looking for me. Her home and the beacon site are off of Shipley Ferry Road south of Interstate 81. As I drove up her driveway I saw her waiting for me at her garage door. I parked and introduced myself. She pointed to the hill behind her sister’s house, and said "that light was on the top of that hill behind my sister’s house." She asked if I wanted her to go up the hill with me and suggested we could drive up the hill in my jeep. She also said her 86 year old sister wouldn’t mind as she was at her exercise class. I thanked her, but said I would walk up the hill. Other than climbing through a barbed wire fence it was an easy trip up the hill. With the leaves off the trees and most of the ground vegetation dead it was easy to find the four tower stubs poking through the leaf debris on the ground. The tower had been located at the very top of the hill. The tower legs were encased in a concrete footer that was above ground level. Other tower legs that I have found did not have any concrete visible above ground, but some were set in a concrete slab, like the one at the Crossville TN airport.

Many airway beacons were located on airports and are still in use today. The beacon on the grounds of the Crossville Tennessee airport is an excellent example of airway beacon construction and photos of the Crossville beacon are included below to show construction details.

Benchmark Interview

Tue, 15 Aug 2006 20:34:28 -0400

August 15, 2006: The following questions were posed by Angus Stocking, editor of the upcoming book Lasting Impressions: A glimpse into the legacy of surveying, in which several of my benchmark photographs and stories are to be published. I am sure the entire “interview” won’t be used in the book; I think it was simply intended to give Angus enough background information to write a short paragraph about me. But after writing it I could see the value in posting it on my site, both to satisfy the curiosity of some of my regular visitors, and possibly to spark some interest in those just passing through.

How did you get into benchmark recovery, and how long have you been doing it?

I first became aware of benchmarks in January 2002 through a now-defunct geocache called the NGS Benchmark Recovery Cache. I went out that afternoon and found my first mark, a triangulation station called SOUTHSIDE, not more than a mile from where I was living at the time. It wasn’t until several months later that the Benchmark Hunting section of Geocaching.com went online, but once it did, I was hooked. And I already had found several more marks in the meantime. From the beginning, I was interested in learning how I could contribute to NGS, and I was pleased to find that they welcome and value my observations. I have currently submitted to their database well over 100 official recovery notes.

What are your motivations?

First and foremost, I’m motivated by discovering the connections these marks give me to surveyors and all others who may have seen them and worked with them through the decades. Investigating these marks takes research, patience, and an eye for the little clues that remain long after the most obvious structures and pathways become victims of time and progress. I am also inspired by the fact that I can contribute to the ever-growing NGS database and that my words and measurements will be useful for years in the future. I also have personal motivations. Benchmark hunting has pushed me to climb to mountain summits with beautiful vistas and creep into hidden city corners I never would have seen otherwise, has introduced me to Monica Lewinsky’s apartment building and C. S. Peirce’s estate, has encouraged me to hike along the Appalachian Trail and the Long Path. I’ve become somewhat a collector of experiences, and my memories, stories and digital photos are more precious than any tangible souvenir. I’ve developed my photography, writing and map-reading skills; have researched old buildings, abandoned streets and rail lines; and have improved my physical health.

What are your goals re: benchmark recovery?

I intend to continue searching for and documenting marks for a long time to come. I aim to maintain a high level of care in documenting the marks I find, so that my entries into the NGS database will continue to be of value to professionals. I have kept full photographic documentation of each mark I’ve found and intend to submit these photos to the database as well, when provisions are made for such entries.

About how many benchmarks would you say you’ve recovered?

My current count is 315, which in addition to simple elevation benchmarks includes marks I’ve demonstrated to be destroyed, as well as triangulation stations (whose auxiliary marks I do not count separately unless they have their own PIDs). I don’t go for the quick finds and big numbers like some “hobbyist” hunters do. I prefer to take my time and do a complete recovery, as well as to seek out some of the more obscure marks. Marks that are not found often require more work than the marks that are easy finds, but they aren’t included in our totals. For various reasons not all marks I find are reported to NGS, the most common of which being that many marks are USGS-only, or there have been no changes to the marks’ descriptions or status in the past year.

What are some notable experiences you’ve had?

The stories are lengthy, but just for some examples: I’ve found marks with errors in their descriptions or measurements, which I was able to note to NGS. I’ve met people who were on-site when triangulation stations were set on their property, and who were all too happy to help me with my own recoveries. I’ve found a bolt set in 1865 which is still in great condition today. I’ve also been challenged, chased away from highway shoulders, and watched with suspicion. Probably the best experiences I’ve had have been when I use the clues I find at the site and the old recovery notes to piece together where a tricky mark must be located, and then poke around in the dirt or shrubbery, and actually find it!

And just for background, what’s your day job, and what are some of your other interests?

I work as a computer systems technician and programmer for an academic library. My main interests are website development, railroads and trolleys, photography, local history, and many outdoor pursuits (hiking, mountain biking, hunting, rock climbing).

Chocolate Benchmarks

Tue, 10 Jan 2006 19:35:28 -0500

Why chocolate benchmarks? While browsing web sites last year I came across some silicone molding compounds that I thought would be fun to play with. I wasn’t sure what to use them for, but it occurred to me that it might be fun to make molds of benchmarks, and then create chocolate treats.

Then I started thinking (as did others around the same time, as evidenced by this Geocaching.com forum thread) that a similar process could be used to make a mold of a mark still in its setting if there was something special about it. (Or if you’re really into it and have a lot of spare time, I suppose you could make a mold of every mark you find and start a collection.) Here is the process I used to create my chocolate benchmarks.

1. Find a Benchmark

Unused gaging station disk

This may be the hardest part! I happen to have quite a few survey mark disks of various types, most of which are unused disks I acquired from surveyors or others in related fields. One was a Destroyed mark that had to be removed from its setting. I also have several 1-inch replica pins such as can be ordered through Mountainclimb.com. You may even want to modify the process and capture impressions of marks in the field.

The disk I’m using for my demonstration was never used in the field. It was sent to me by a USGS employee with whom I’ve corresponded on an urban exploration forum.

Make sure the disk is clean before making the mold.

2. Make the Mold

Jars of silicone molding material.

Possible molding materials abound, depending on how much time you have to make the mold, what you plan to do with it, and how long you’d like to keep it.

I chose Culinart’s Silicone Plastique, a food-safe silicone molding compound, because I planned to use the molds for chocolate and other goodies. I also liked the fact that the silicone will produce flexible molds that are heat- and cold-resistant. [2025 edit: It appears that Silicone Plastique is no longer available, but any food-grade mold making silicone putty like EasyMold should work just as well.]

a. Measure the molding compound

It's almost like baking.

For this four-inch disk, I used approximately 2.5 tablespoons of each component. The catalyst (blue) and base (dull white) need to be mixed in equal parts.

b. Mix it together

This still needs to be mixed and kneaded some more.

The components need to be mixed until a uniform light-blue color is reached. I do this slowly so I don’t introduce too much air into the mixture. Once the two are mixed, you’ve got about twenty minutes to work and an hour until the silicone fully cures. It’s sticky, so I lined the board with waxed paper.

c. Fill in the details

Spreading on a thin layer.

It’s best if you fill in the fine details first with a thin layer. Be sure not to trap air bubbles beneath the silicone.

An offset spatula might help, or just use your fingers.

d. Complete the mold

Smooth up the sides.

Form a ¼-inch thick patty from the remainder of the silicone and press the mark down into it. Then smooth the sides of the mold up to conform to the edges of the mark.

The finished mold.

Let it sit for at least an hour for the silicone to cure, then peel away the mold. (Test it first by trying to press a fingernail into the outer edge of the mold, just to make sure it has solidified.)

3. Make the Chocolates

a. Melt the chocolate

For the best appearance and taste, buy real chocolate and learn how to temper it. Did I do this? No, at least not yet. I used quick-melting candy wafers that are available in most arts & crafts stores.

If you’re using candy wafers, just follow the manufacturer’s directions. Generally they’ll melt in a few seconds in the microwave. Or if, like me, you don’t have one of those newfangled contraptions, they’ll melt equally well in a double boiler. And if, like me, you don’t have a real double boiler, you can make one out of a shallow metal bowl set atop a deep pot half-filled with simmering water. You’ll figure it out.

b. Fill the mold

Filled mold

Pour the melted chocolate slowly into the mold. Lifting the mold a few inches and dropping it on the counter several times will help release any air bubbles that may have formed.

As you can see, some chocolate spilled over the sides. It’s very easy to remove the excess after the chocolate hardens.

c. Chill and unmold

The finished disk!

Refrigerate 20-30 minutes or until chocolate has hardened, and then pop out your chocolate benchmark! They go very well with tea and shortbread cookies.

About Survey Mark Hunting

Sun, 16 Aug 2026 21:31:00 -0400

The What

NGS Triangulation Station BEAUTIFUL

Survey marks or monuments are objects used to mark a precise location and/or elevation on the earth. The markers most survey mark hunters look for most often are 4-inch brass or aluminum disks installed into a stable setting like bedrock, an embedded boulder, a specially-poured concrete monument, a large building or bridge. Earlier survey monuments were made of stone or even buried bottles or jugs.

Some other types of survey marks are also included in the database, such as landmark stations—tall structures that can be sighted on from a distance so that trigonometric calculations can be made. Airway beacons are of this type.

Survey mark hunting, sometimes referred to as “benchmark hunting” regardless of the type of marker being sought, is simply the activity of searching for these survey marks. When we find, or “recover,” a mark, we do not take it or disturb it in any way. We document the mark’s condition and make note of any updates to the description and geographic coordinates that we think are needed. Then, when applicable, we send our report to the National Geodetic Survey (NGS) or the U. S. Geological Survey (USGS).

The Why

These markers are simultaneously a link to the past and part of a stable network from which much of our modern progress emerges. They are tangible evidence of the importance of knowing your position and being able to describe it accurately and were the culmination of centuries of work toward that end. They were also a step toward the now-ubiquitous technology of GPS, a technology that ultimately brought the accurate knowledge of place into the hands of people worldwide and made it a part of our everyday lives.

Sorting through layers of history as I try to find these markers brings me a knowledge of my local area and other areas I visit—a knowledge more intimate and exciting than can be gleaned from history books or visits to tourist sites. We learn where the old one-room schoolhouses were, learn about how air navigation worked decades before GPS (and even prior to radio communications!), find stones from the foundations of long-gone homes, and trace the still remaining paths of railroads that built this country and are now overgrown.

It’s also an inspiration to me to think of the early surveyors setting out across truly untouched wilderness or pioneer aviators flying off into the night, having to submit to being unsure at any given time exactly where they were or how conditions would be upon their arrival or attempted landing. It puts my own fears into major perspective.

The How

Explore the resources on the Survey Mark Hunting page to get started!

The Disclaimer

I am not a surveyor, nor have I ever been one. I haven’t even played one on TV. (Although I’m sure I would be a better surveyor than I would an actor.)

This site is intended to be a catalog of my own adventures in finding survey markers and a resource for others who wish to have survey mark hunting adventures of their own. It is meant to share the excitement of the hunt as well as the maps, documents, and other knowledge sources that I use to zero in on the locations of these marks.

It’s very satisfying to hear that surveyors find my work on these pages helpful—many have reported that they use the collection of local control monument databases—and I report my finds (and most unsuccessful attempts) to NGS and USGS so that they may update their official databases. But because I haven’t actually worked in the field, I can’t give an expert opinion about the condition of markers or their settings. And I can’t vouch for the legality of access to any survey mark, as conditions and property boundaries can change at any time. I am, however, sincere in my efforts and try my best to convey an accurate sense of the marker’s condition as well as a description of its surroundings, ease of access, and possible future threats to the stability or accessibility of the mark.

Airway Beacons List—Eastern U.S.

Sun, 16 Aug 2026 21:31:00 -0400

Last updated August 16, 2026

For airway beacons in the western U.S., see: Airway Beacons List—Western U.S.

The following is an incomplete list of airway beacons and arrows. The original list, compiled by Roger Barnes in 2003, was drawn from the NGS database of survey marks. In recent years, many other contributors have shared their knowledge and added other beacon and arrow sites to the list. Many of these beacons no longer exist, but their locations and remains are of historical interest.

Any item that does not have a PID is not in the NGS database but was discovered by other methods.

	Beacon tower at Malad City Airport, ID	ID	ONEIDA	42.16628	-112.287262	MALAD CITY WEST				Y	Y		Updated non-NGS beacon/arrow	Kaarin provided information to Arrows Across America. According to the 1932 Airway Bulletin, there was once an arrow, but it is not visible today. It seems that over time, the number changed to 9. No arrow, beacon and generator shed remaining, as of 10/15/2016. Reported by Kaarin Englemann.

	Destroyed/re-purposed site near Mountain Home, ID	ID	ELMORE	43.0623	-115.53624	REVERSE							Updated non-NGS beacon/arrow	Destroyed/Re-purposed, as of 5/4/2015. Details: Scaled the rough location shown on the 1936 Airway Map No 135, and correlated it with a USGS topo quad. Field search located a locked fenced in radio tower on the site, which is on top of a small hill along with a USGS monument (OZ1033) which the datasheet referenced Airway Beacon 23 with an azimuth and distance. It appears that the tower was removed, as the structure is similar, but not the same as the Internation Derrick & Equipment towers. Reported by Glen Smallwood.

Details from Glen Smallwood: Did not find any evidence of a concrete slab or arrow at the surface, even under the tower. There was a graded area to the east where a shed would have been. There was no real road access to the site, which probably has helped keep the beacon lens intact. Tower manufacturer was the same as was found at Beacon 25 in Mountain Home. The controller box was manufactured in Switzerland, with a patent date of 1916. Details from Charles W. Voll: Google Earth imagery dated 5/9/2015 shows what appears to be a tower with out an arrow or concrete pad for building. Tower appears to be the same kind used for the airway beacons. Reported by Glen Smallwood and Charles W. Voll.

PAUL-MINNEAPOLI	33 OLD 37	N	Concrete		Updated NGS beacon/arrow	Arrow complete and intact, tower and generator shed gone. Per the current owner Jim, whose father bought the land in 1920, the beacon was built in 1928 and at some point in the 1950's the mechanism that turned the light on at dusk and off at dawn failed and they had to manually switch it on and off. After doing this for some time due to parts unavailability the beacon was deactivated and the tower and generator shed were removed. The arrow is clearly visible in Google Maps. The angle of the tip of the arrow is not an artifact nor a sign of damage. It was built that way. Reported 10/29/2019 by Don Butner.

There is a shed nearby which may be the original, slightly relocated. The arrow isn't obvious. 2013 satellite images show the tower on its side on the ground a short distance from its original location. I can't find any more recent photos. Tower may or may not be standing, shed possibly nearby, no arrow obvious. From Kerri Rempp, Chadron Record editor: "I checked with the city public works director who responded that the old tower has been sold, but the buyer is keeping it in one piece with the intention of setting it up at a later date." So the tower was removed from the airport in 2013. Reported by Brian Lee.

Airway Beacons

Why airway beacons?

Light for the Night Air Mail

Why airway beacons, on a site dedicated to survey marks?

Apart from their obvious connection as objects that helped to build the current American infrastructure, airway beacons and survey marks are connected in another, more obscure way: through the National Geodetic Survey database.

In 2003 a fellow geocacher/survey mark hunter, Roger Barnes, asked if I would host a survey mark-related list on my web server space. He explained that he had pulled out all of the entries classified as airway beacons from the NGS database.

I was happy to post the lists and over the years I’ve maintained the content, most recently adding a map of beacon locations and accepting new and updated beacon information.

The airway beacons’ primary purpose was to provide a nighttime navigation system for early aviators, particularly for the U. S. Air Mail service, beginning in the 1920s. It’s true that the U.S. Coast & Geodetic Survey (precursor to NGS) was involved in early airway mapping. But the list of beacons drawn from the NGS database is not complete, and the beacons in the database are included primarily because they served as landmark stations. Still, to my knowledge it is the most extensive “catalog” of beacon locations, data that otherwise might have been lost to time and definitely would have been very difficult to piece together from other sources.

Roger’s lists have generated a lot of discussion among aviation enthusiasts and people who enjoy hunting the beacon towers and associated concrete arrows just like I enjoy searching for survey marks. I’m no expert on the topic but I have gathered some resources over the years, and I know several people who are extremely knowledgeable on the topic. Please contact me if you have questions or something to contribute!

Beacon Lights

from Instrument Flying by P.V.H. Weems and Charles Zweng, published 1940.

Standard beacon installation

The original standard airway beacon is a 24-inch rotating unit of the searchlight type with approximately 1,000,000 candlepower. The new standard airway beacon is a 36-inch rotating unit showing two beams of light separated by an angle of 180, each beam having a maximum of about 1,250,000 candlepower. The airway beacons are so operated as to show six clear flashes per minute. A directional arrow seventy feet in length, which points to the next higher numbered beacon light, is constructed on the ground at the base of the beacon tower. On the feather end of the arrow, or on one side of the roof of the small power house, the beacon-light site number is painted. Beacons are numbered from west to east or south to north, between terminal cities, the numbers corresponding in each case to the nearest ten-mile interval.

In the case of beacon installations where rotating beacons showing only clear flashes (rotating beacons without color screen) are in use, course lights are generally installed to provide the auxiliary color flashes, the presence of landing facilities being indicated by green flashes and the absence of such facilities by red flashes. Two course lights are mounted on each beacon tower, one pointing forward and the other pointing backward along the airway. These course lights are searchlight projectors fitted with aviation red or green lenses and giving a beam of fifteen degrees horizontal and six degrees vertical spread and of about 100,000 candlepower. Each course light flashes its code signal, which corresponds to the number of the beacon on the airway. The course lights flash code numbers running from one to ten, and thus indicate successive 100-mile sections of the airway. In order for a pilot to identify positively the number of a beacon site or the miles he has flown along the airway from the code characteristic, it is necessary for him to know on which 100-mile section he is flying.

Historical Airway Maps

Maps of early aviation routes in the United States

All maps were digitized and made available by the Library of Congress, and each link will take you to the appropriate map in their digital collection. I’ve created this index because their collection of airway maps does not contain individual metadata and is therefore difficult to search.

Note: These maps are for historical research purposes only. They are not intended for use in navigation.

Objects Used as Landmarks

Objects used as landmarks

The following classifications, which include most landmarks, are defined and accompanied by remarks to standardize their use. These names shall be used so far as practicable.

BUILDING: (See House.)
CHIMNEY: That projecting part of a building for conveying smoke, etc., to the outer air. This term is to be used only where the building is the prominent feature and where charting of some specific part of it is desirable; for example, the chimney of a large factory.
CUPOLA: A small turret or dome-shaped tower rising from a building, in cases where the building is the prominent object and where the cupola is small as compared to the building.
DOME: A large cupola of rounded hemispherical form, or a roof of the same shape, whether it is actually rounded or many-sided.
FLAGPOLE: A single staff flagpole rising from the ground and not attached to a building.
FLAGSTAFF: A single staff flagpole rising from a building. This is not desirable is a landmark, due to its nonpermanence. Although it is desirable that the most definite part of a building (such as the flagstaff) be pointed at in making observations, this is not necessarily the most important part for charting purposes. Wherever possible give, for use on the chart, that part of the building from which the flagstaff rises, as TOWER, CUPOLA, DOME, etc.
FLAG TOWER: Any scaffold-like tower on which flags are hoisted, such as a Coast Guard skeleton steel flagpole or a Weather Bureau signal tower. Do not use Signal Tower.
GAS TANK or OIL TANK: Since these differ in shape and size from a water tank, the compound name will be used.
HOUSE or BUILDING: Although it is desirable to locate a house or building by observations on a specific point, as the west gable or the flagstaff, such terms are not desirable for charting purposes, where it is the structure itself which is the landmark. Use HOUSE or BUILDING followed by a description of the point in either capitals or lower-case letters, according to whether it should be used on the chart or not. Where the outline of the building should be shown on the chart, the following notation-“chart outline”-should be made on Form 567.
LOOKOUT TOWER: Any tower surmounted by a small house in which a watch is habitually kept, such as a Coast Guard lookout tower or a fire lookout tower. Do not use this term in describing an observation tower, or a part of a building in which no watch is kept.
MONUMENT: Do not use Obelisk or other terms.
OIL TANK: (See Gas Tank.)
RADIO MAST: A general term to include any tower, pole, or structure for elevating antennas.
SPIRE: In general, any slender pointed structure surmounting a building. The spire is rarely less than two-thirds of the entire height and its lines are rarely broken by stages or other features. Do not use Steeple. Spire is not applicable to a short pyramid-shaped structure rising from a tower or belfry.
STACK: Any tall smokestack or chimney, regardless of color, shape, or material, if the stack is more prominent, as a landmark, than any buildings in connection with it. Do not use Chimney.
STANDPIPE: A tall cylindrical structure, in a waterworks system, whose height is several times greater than its diameter.
TANK: A tank for holding water, when its base rests on the ground or other foundation, and its height is not much greater than its diameter.
TANK (ELEVATED): A tank for holding water, where such tank is elevated high above the ground or other foundation by a tall skeleton framework.
TOWER: (a) A part of a structure higher than the rest, but having vertical sides for the greater part of its height.; (b) An isolated structure with vertical sides (not otherwise classified), high in proportion to the size of its base, and of simple form.; (c) The top of a skyscraper, high in proportion to its horizontal size and rising above its surroundings.; (d) Any structure, whether its sides are vertical or not, with base on the ground and high in proportion to its base. Its sides may be open framework, such as a Bilby steel tower.
TREE: Do not use Lone tree or Conspicuous lone tree. This is assumed, otherwise the tree would not serve as a landmark.
WATER TOWER (infrequent): A decorative structure enclosing a tank or standpipe, or used as such, when by its appearance it would not be recognized as such.
WINDMILL: A self-explanatory term.

Specifications For Marks

3. Naming of stations. – The triangulation party normally uses the name assigned by the reconnaissance party unless there is some reason for changing it. Correct spelling of the name should be checked locally before the mark is stamped. The correct name as stamped on the mark will be used throughout the records.

The name of the locality is preferable but the name of the property owner may be used for the designation of the station. To avoid ill feeling, it should be made certain that the station is actually on the named property, and that the owner’s name is correctly spelled.

Double names should be avoided if practical as they cause extra work throughout the recording and computing. Also the double name including the word “peak,” or “mountain,” or “point,” is not usually necessary, since the description should state that the station is on a peak or mountain or point of that name.

Names of stations of other organizations should be retained exactly as stamped on that organization’s station mark. If additional azimuth or reference marks are established by a party of this Bureau, the stamping should include the original station name, the initials of the other organization, and the year in which the additional marks are established.

If the name of a recovered intersection station (not marked with a bronze disk) is incorrect, the correct name should be typed in the heading of Form 525b. The first statement in the body of the note should then list any previous triangulation names of the same object, as well as map names and any other names in current usage.

Chapter 6.-APPENDIX

BOARD OF SURVEYS AND MAPS SPECIFICATIONS FOR HORIZONTAL AND VERTICAL CONTROL

The following “Specifications for Horizontal and Vertical Control” were agreed upon by the various Federal surveying and mapping agencies through the approval of the Board of Surveys and Maps of the Federal Government on May 9, 1933. Although this Board was abolished in 1942 by Executive Order (No. 9094), the basic classification of triangulation is still applicable. However, the entire specifications are reproduced here for general information only and are not to be considered as modifications of the instructions contained in the preceding chapters of this manual.

Control surveys to determine the latitude, longitude, and elevation of marked points distributed throughout an area to be mapped are necessary as a basis for all topographic, hydrographic, and cadastral surveys that cover regions of considerable extent. The control surveys should also be so designed as to give the maximum benefit to those conducting general engineering operations on a large scale.

TRIANGULATION

First-order Triangulation.-Triangulation of the first order should be executed in belts about 120 miles apart over the region to be surveyed, except under such conditions as may require the substitution of first-order traverse. Triangle closures should rarely exceed 3 seconds, and the average closing error should be not greatly in excess of 1 second. The discrepancy between the measured length of a base line and its length as computed through the triangulation from the next preceding base, after the side and angle equations have been satisfied, should not exceed one part in 25,000. Laplace stations should be selected at intervals of from 6 to 10 figures along the scheme. The accuracy of azimuths to be observed at such stations should be limited to a probable error rarely exceeding 0.3 second.

Second-order Triangulation.-Triangulation of the second order (or traverse of corresponding accuracy) should be used to subdivide the areas between belts of first-order control so that no point in such an area will be farther than about 10 to 15 miles from some station of either first-order or second-order accuracy. Triangles of second-order triangulation should close with an average error not greater than 3 seconds and a maximum error seldom exceeding 5 seconds, provided that, where single triangles are necessary, the closures shall not exceed 4 seconds. Closures in length on lines of the first-order net, on second-order lines previously adjusted, or on base lines, should not exceed one part in 10,000, after the side and angle equations have been satisfied. Arcs of second-order triangulation will, in general, not exceed 150 miles in length. One Laplace station should be selected near the center of a second-order arc of triangulation which is between 120 and 150 miles in length. Should an arc be longer than that, a Laplace station should be located at intervals of from 8 to 15 figures. The accuracy of the azimuth observations at such stations should be limited to a probable error rarely exceeding 0.5 second.

Third-order Triangulation.-Triangulation of the third order is ordinarily used for the immediate control of topographic and hydrographic surveys. Extensions of third-order triangulation or of third-order traverse, from triangulation or traverse of a higher order, should be made so as to control the entire area to be surveyed. Triangles of third-order triangulation should close with a maximum error of 10 seconds and an average error seldom exceeding 5 seconds. Closures in length on lines of first-order or second-order triangulation, on lines of third-order triangulation previously adjusted, or on base lines, should not exceed one part in 5,000, after the side and angle equations have been satisfied.

Fourth-order Triangulation.-Triangulation (or traverse) of the fourth order is used to connect the control of higher grades with the detailed surveying and mapping operations in a region. It should start from control of a higher grade and should never be carried for more than a few figures without being again connected to a control station of a higher accuracy than fourth. It may be performed with a plane table, transit, or sextant. The sole requirement of accuracy in fourth-order triangulation is that positions of points must be located with error too small to be appreciable on the resulting map.

Note: The specifications listed above were in effect in 1933. They have been modified since then so that now the recommended practice is to establish at least one control station in every 7-1/2-minute quadrangle.

BASES

Accuracy.-Bases for the control of the lengths of first-order triangulation should be measured with an accuracy represented by a probable error of not more than one part in 1,000,000 and an estimated actual error of not more than one part in 250,000 or 300,000. On second-order bases the probable error should not be greater than one part in 500,000 and the estimated actual error not greater than one part in 150,000. On third-order bases the probable error and estimated actual error should not be greater than one part in 200,000 and one part in 75,000 respectively. Any methods and instruments may be used which will secure the prescribed results. (For a statement describing what is meant by “probable error” and “estimated actual error” see appendix at the end of these specifications.)

Frequency.-The strength of figures in the triangulation between bases should be considered in determining the distance between bases, according to the method prescribed in U. S. Coast and Geodetic Survey Special Publications Nos.93 and 120.The allowable limit for the summation of R₁ of the individual figures between bases for first-order triangulation should not exceed 80; for the second-order 100; and for the third-order 125, though, where a base site cannot readily be found these limits may be exceeded by 25 percent. The limit prescribed for the agreement between the measured length of a base and its length as computed from the preceding base is the controlling factor, and it may necessitate at times measuring an additional base or strengthening the triangulation between bases.

TRAVERSE

Traverse will be used, in general, only where the cost of triangulation would be excessive because of low relief and heavy timber. Traverse has the advantage of leaving marked points in locations where they are easily accessible, but it is inferior to triangulation in its checks against blunders, and it does not give control over so large an area as a belt of triangulation. Ordinarily, therefore, triangulation should be preferred to traverse on control of the two higher grades if its estimated cost does not exceed the estimated cost of traverse by more than 50 percent. For the third-order control the choice between triangulation and traverse will be determined by the local conditions, and the comparison of cost should be made on an equal basis.

Traverse of all grades of accuracy should be run in loops or connected at each end to triangulation or to traverse of the same grade as that which is being executed or of a higher grade. No traverse lines that are not thus connected or checked should be used for map control. On traverse of the two higher orders marked stations should be established at intervals of not more than 5 miles and with an average of 3 miles or less. Where a marked station occurs on a traverse, one of the adjacent stations should also be marked, in order that the distance and azimuth may be made permanently available, as well as the geographic position.

Accuracy.-First-, second-, third, and fourth-order traverse should be executed with an accuracy comparable with that of triangulation of the corresponding grades. Ordinarily, the traverse methods will give a greater accuracy for the distance between stations than the triangulation method, but it is relatively weaker in the azimuth obtained. The error of closure in position of a first-order traverse line when run in a closed loop or when starting from adjusted triangulation and ending upon adjusted triangulation should not exceed one part in 25,000 of the length of the traverse line after a preliminary adjustment has been made of the azimuth discrepancies between the stations where astronomical azimuths have been observed. This error in position may be somewhat exceeded when the length of the traverse line is small compared to the length of the arc of triangulation between the points where the traverse starts and where it ends, as there may be an appreciable error remaining in the triangulation after adjustment. On first-order traverse an astronomical azimuth should be observed at intervals of 10 to 15 stations, on second-order traverse at intervals of 25 to 40 stations, and on third-order traverse at intervals of 50 to l00 stations. The astronomical azimuth should be determined with an accuracy represented by a probable error of 0.5 second for first-order traverse, 5.0 seconds for second-order traverse, and 30.0 seconds for third-order traverse.

MARKING OF TRIANGULATION AND TRAVERSE STATIONS

Stations of either first-, second-, or third-order accuracy on triangulation and traverse should be marked by tablets of some noncorrodible metal set firmly in posts of concrete, or in large boulders or outcropping bedrock, but where a station is on a building suitable marks of a different character may be used. The tablets may be set in place by means of cement, sulphur, or lead. The concrete posts should be not less than 8 inches in diameter and should extend 30 inches below the surface of the ground. They should have the shape of a truncated prism or cone, in order that the lower end may be larger than the upper and thus better able to resist the lifting effect of frost action. For the same reason the post should be smoothly molded for the upper 10 or 12 inches of the part beneath the surface. Particular care should be taken to insure that the materials used in making the concrete are clean and well mixed. The top 12 or 15 inches of the post should be at least equivalent in strength to a 1-2-3 mixture of cement, sand, and stone; the base may be made of a somewhat leaner mixture. Where a boulder is used it should be at least as large as the concrete post prescribed and should extend to a similar depth beneath the surface. Where the tablet is to be set in bedrock care should be exercised in selecting rock that is of suitable durability, and also to make sure that what is apparently bedrock is not a small detached mass of rock.

Special Marks.-Under certain conditions special marks may be used. Where no large boulder or bedrock is available at a station and where by its location it would be unduly expensive to construct a concrete mark, a metal pipe of suitable size and of noncorrodible material may be used. The base of this pipe should be so shaped as to resist extraction of the pipe and should preferably be set in concrete. In swamps a long metal pipe, set inside a drain tile filled with hydraulic cement, may be used. Where a station mark must be set on land subject to cultivation it is better to have the top of the post entirely below the depth which can be reached by a plow-that is, about 12 inches below the surface. Where a mark of this type is set it is necessary that measurements to the center of the roadways, section lines, etc., be made in sufficient number to enable one seeking to recover the mark in the future to determine its location within a few feet. The mark itself can then be found by digging or by prodding with an iron rod.

Subsurface Marks.-Where a concrete post is used a subsurface mark should be set if possible. This mark should preferably be made of concrete, not less than 6 inches thick and 10 inches in diameter, with the station point marked by a metal tablet, copper bolt, or other durable substance. The subsurface mark should be 4 or 5 inches below the base of the concrete post, and extreme care must be taken that the subsurface mark is directly underneath the surface mark.

Reference Marks.-At least one and preferably two reference marks should be set at each station. They should be metal tablets set in concrete posts, boulders, or bedrock. The metal tablets used for the reference marks should have a different inscription upon them than the station tablets and preferably should bear an arrow pointing toward the station. Where more than one reference mark is used at a station, they should be stamped and numbered serially, clockwise as viewed from the station. Particular care should be taken in selecting sites for these reference marks where they will not be subject to disturbance. Fence lines or section lines are suitable sites.

Azimuth Marks.-At each first- or second-order triangulation station at least one azimuth mark should be established in addition to the reference marks. The mark should be, if practicable, at least 1/4 mile distant and visible from the ground at the triangulation station. It will not be required to measure the distance between the azimuth and station marks. However, the description of the azimuth mark should be sufficiently definite to enable one to recover it with ease. The directions to azimuth marks should be obtained from at least two positions of the circle. Where possible, additional azimuths of objects, such as church spires, cupolas, etc., visible from the ground at the station should be determined.

Third- and fourth-order triangulation usually consists of short lines and is extended into areas so that many of the stations are intervisible from the ground, thus making available azimuths directly between main-scheme stations and obviating the necessity for azimuth marks. Where main-scheme stations are not intervisible azimuth marks should be established. The accuracy of the directions to azimuth marks should be such that azimuths may be obtained with a probable error not in excess of 15 seconds.

Preservation of Station Marks.-The destruction of station marks that are in the way of public improvements is frequently unavoidable. By far the greater number of marks removed, however, are destroyed by malicious or thoughtless persons and this destruction represents a large economic loss to the Government. The restoration of the marks in even a small region will sometimes cost several thousand dollars, not counting the inconvenience caused to local engineers and surveyors by the lack of stations upon which to base their surveys.

There is a Federal law imposing a fine or imprisonment for the destruction of a Federal station mark, but it has never been enforced. Many States have laws directed to the same end, but even under State laws it is very difficult to secure a conviction. Such laws, however, have a notable restraining effect. It is very desirable that all the States should have laws imposing penalties for destruction of marks established by Federal surveys, and also prescribing the terms upon which Federal surveyors shall have the right of entry upon private property, together with methods for reimbursing the owner of the land for any damage sustained by such entry.

The best way of protecting station and bench marks seems to be by educating the people to understand the value of these marks. To that end as great publicity as possible should be obtained when work is being conducted in a region, to make known to the inhabitants the purpose and value of the surveys and the function of the marks in perpetuating the surveys. This publicity can be obtained by the insertion of articles in local papers, by the distribution of pamphlets illustrative of the purpose of the work, and by conversation with influential people or with owners of the land upon which the marks are located.

Selection of Names.-The name of a triangulation or traverse station should be stamped upon the metal tablet, preferably before it is set into the concrete or stone. The name should not be duplicated within the confines of a county. Names for triangulation and traverse stations should have a geographic significance wherever possible. Care should be taken by the chief of party to ascertain the name which is most prevalent for a particular geographic feature, for frequently a mountain or stream will have different names in the same region. In particular, officials of the Forest Service should be consulted regarding the names of topographic features within national or State forests or in regions adjacent thereto.

Program for Control Surveys.-First- and second-order triangulation and traverse should be completed in a region before the third-order control is developed. It is also an advantage, though not always practicable, to have the third-order control completed and computed before topographic surveys are begun in a region, in order that a better distribution of the topographic working parties may be made.

Description of Station.-A clear, concise, and complete description of each triangulation and traverse station established should be made out and filed in convenient form in the district or central office of the organization making the survey. Where search is made for a triangulation or traverse station established in a previous year, a note to that effect must be entered on an appropriate form. If the station is found, the recovery note should state the condition in which the mark was found and should give any modifications or additions to the description which would make the station more easily found in the future. If the station is not found, the note should indicate the thoroughness of the search made and give recommendations as to whether or not the station should be marked “lost” in the records.

Report of Recovery of any Federal Survey Mark.-Member organizations of the Board of Surveys and Maps should instruct their field officers to report upon the condition of station and bench marks visited by them which were established by another member organization. If a properly equipped field party of a member organization finds in poor condition a Federal triangulation or traverse station mark of a third or higher order of accuracy and if its proper location can be determined with certainty and accuracy, either by a recovered underground mark or by measurements from two or more reference marks, the party should re-mark the station if practicable. If the tablet marking the original station is recovered, it should be reset. If an underground mark exists due care must be exercised to insure that the new surface mark is exactly centered over the subsurface mark.

A leveling bench mark should not be replaced or repaired. When a bench mark is found in poor condition by a field party from some organization represented on the Board of Surveys and Maps, a new bench mark may be established nearby, and its elevation determined by leveling from the original mark. A copy of the field notes for obtaining the elevation of the new mark should accompany the description of the new mark.

The report of the recovery of the station or bench mark, or the revised description, should be sent through official channels to the organization that established the original mark.

Elevation of Station.-The elevation above mean sea level datum should be determined for each triangulation and traverse station and for permanently marked intersection stations. The elevation of triangulation stations need be determined with only such accuracy as will enable the reduction of the directions and distances to mean sea level. It is very desirable that the elevation of first- and second-order traverse stations be determined by spirit leveling.

High Towers.-The use of high towers for instrument supports should be avoided wherever possible, both because of their expense and because usually the station cannot be used for future work without rebuilding the tower. Where local conditions make it necessary to use a tower, an azimuth mark should invariably be established in order that traverse lines may be joined to the station without the delay and expense of rebuilding the tower. If a permanent natural object is not available, an azimuth mark should be established not less than 500 feet distant from the station, in a location where it will be visible from the ground at the station. Whether a natural or artificial mark is used for the azimuth mark, it should be fully described, and either its measured or estimated distance from the station mark should be given.

Publication of Results.-Resulting positions, descriptions, and elevations of stations, together with their azimuths and distances to other stations, should be published as soon as possible and in compact form. All positions for horizonal-control stations must be given by latitude and longitude, referred to the North American datum of 1927, if possible.

Each publication containing leveling or triangulation data should include two small index maps, one of a section of the country showing the areas covered by the data in the publication, and another of the whole country showing the areas covered by each previously published report of a similar nature with reference to the numbers or names of the reports.

Density of Distribution.-The distance between belts of first- and second-order triangulation and traverse has already been specified. Third-order triangulation and traverse, which have for their function the control of detailed surveys in a region, should provide a density of distribution of stations sufficient to enable the topographer or the hydrographer to obtain the required accuracy without undue delay or expense. The nature of the terrain will determine the density of distribution of stations. No 15-minute quadrangle or area of similar extent should, however, have less than three horizontal-control stations of the third or higher order of accuracy. As many more should be established as will fulfill the requirements of the topographer. If traverse is being carried on instead of triangulation, marked traverse stations should be left at intervals averaging not more than 3 miles. The requirements of the topographer should be borne in mind on traverse as well as on triangulation.

In executing traverse or triangulation of the three higher orders particular effort should be made to locate additional stations by the intersection method. These additional stations may be either existing objects, such as water towers, church spires, or specially marked points.

The stations that are to be available for future recovery and use should be selected with two things in view-first, their use by the topographer or engineer working from the ground, and, second, their use on revision surveys by the aerial photo-topographic method. The second purpose requires as many stations as possible that could be identified from the air without special marking.

LEVELING

CLASSIFICATION:

First-order Leveling.-First-order leveling should be used in developing the main level net of the United States. The lines should be so placed that eventually no point in the country will be more than about 50 miles from a bench mark established by leveling of this order. All the lines should be divided into sections 1 to 2 kilometers in length, and each section should be run forward and backward, the two runnings of a section not to differ more than 4 mm.√K or 0.017 foot √M, where K is the length of the section in kilometers and M its length in miles.

Second-order Leveling.-Second-order leveling should be used in subdividing loops of first-order leveling until no point within the area is much more than 12-1/2 miles from a first- or second-order bench mark. Second-order leveling will include lines run by first-order methods, but in only one direction, between bench marks previously established by first-order leveling and all double lines of leveling whose sections, run in a backward and forward direction, check within the limits of 8.4 mm.√K or 0.035 foot √M where K is the length of the section in kilometers and M its length in miles.

Third-order Leveling.-Third-order leveling may be used in subdividing loops of first- or second-order leveling, where additional control may be required. Third-order lines should not be extended more than 30 miles from lines of the first or second order; they may be single-run lines but must always be loops or circuits closed upon lines of equal or higher order. Closing checks are not to exceed 12 mm. √(kilometers in circuit), or 0.05 foot √(miles in circuit).

Leveling of Lower Order.-Leveling that allows closure checks greater than the limit stated for third-order work, such as trigonometric leveling, barometric leveling, or “flying” levels, shall be considered as belonging to the lower order of work. No bench marks established by leveling that is less accurate than that of the third order, as above described, shall be marked by standard bench-mark tablets, except that in mountainous regions inaccessible to ordinary spirit-level lines standard marks may be used on mountain summits to mark elevations determined by trigonometric leveling; such marks should be stamped in a distinguishing manner. Elevations inferior to the third order in accuracy shall not be published in such a way as to be confused with standard work of the third or higher orders.

Bench Marks.-All first-, second-, and third-order level lines should be adequately marked by monuments, at average intervals of not more than 2 miles, preferably by metal tablets set into concrete posts, substantial buildings, outcropping rock, or large boulders. At places from which it is likely that future leveling lines will be extended, at least three bench marks should be established within a radius of about a half a mile, but far enough apart not to be affected by the same disturbing causes. In addition, supplementary marks on trees, bridge seats, and similar places should be left for each mile of line. In each city or town through which a line of levels passes, at least two permanent bench marks should be established, the number of bench marks for cities of large population being somewhat in proportion to the size of the city.

New leveling should be tied to bench marks of previous leveling by Government and other organizations wherever practicable, to furnish checks and provide means of correlating results.

An effort should be made to have level lines run over the routes where traverse stations have been established, in order that the elevations of those stations may be determined.

All metal bench marks should, at the time they are established, have stamped upon them some mark which will positively identify them.

A complete description should be made of each old bench mark visited.

Elevations.-All elevations should be based on mean sea level datum.

Elevations of all bench marks required by existing law (20 Stat. L., 435) in areas to be topographically mapped should be determined by leveling of the first, second, or third order or, in mountainous country, by trigonometric leveling.

Elevations above mean sea level should be stamped on each bench mark, but not until the office computations and adjustments have been made.

Publication of results.-The adjusted elevations and the descriptions of bench marks of first-, second-, and third-order leveling should be published as promptly as possible. The elevation in feet and, if desired, in meters also and the description of each bench mark should be printed on the same page.

Each publication containing leveling data should include two small index maps, one of a section of the country showing showing the area covered by the data in the publication and another of the whole country showing the areas covered by each previously published report of a similar nature, with references to the numbers or names of the reports.

The publication of the results of long spur lines of first-order leveling should await the extension of the spur line to previously established bench marks, in order to insure the results against any gross errors in the work.

CLASSIFICATION OF CONTROL

The foregoing data concerning control classification may be tabulated as follows:

	First Order	Second Order	Third Order	Fourth Order
Triangulation	Average triangle closure 1″, check on base 1/25,000.	Average triangle closure 3″, check on base 1/10,000.	Average triangle closure 5″, check on base 1/5,000.	Plane table or transit.
Traverse	Position check 1/25,000.	Position check 1/10,000.	Position check 1/5,000.	Stadia, tape, or wheel.
Leveling	Error of closure of section 0.017 ft. √miles or 4 mm.√kilometers.	Error of closure of section 0.035 ft. √miles or 8.4 mm.√kilometers.	Error of closure of circuit 0.05 ft. √miles or 12 mm.√kilometers.	Flying wye levels, vertical angles.

FIELD COMPUTATIONS

In order to insure the requisite degree of accuracy for each grade of work and to avoid the necessity of going over lines a second time to correct excessive errors, certain field computations will be necessary, but these are invariably to be considered preliminary only. On triangulation, eccentric stations should be reduced to center, spherical excesses computed, and triangle closures tested as soon as possible after the angles are measured; and distances should be computed to see that the lengths check properly through the triangulation figures.

Sufficient computations should be made for base-line measures to show whether the forward and backward measures check within proper limits, and the length of the base should be reduced to sea level from elevations determined in the field. In this way it can be learned whether the length as carried by the triangulation checks with the measured lengths within the limits required for the particular grade of work.

A progress sketch should invariably be made by the field party, whether engaged on triangulation, traverse, or leveling.

Least-square adjustments should never be made in the field.

In first-order and second-order traverse it is necessary to carry the computation far enough to check the azimuths carried by the traverse with the observed azimuths. If this is not done in the field, the office computation should closely follow the field work.

The field computations for leveling should be sufficiently complete to insure the requisite degree of accuracy for each grade of work. For each bench mark established or touched upon, a complete description should be written and the elevation computed on mean sea level datum.

RECOMMENDATIONS

Each organization to which may be delegated the task of carrying forward control of any of the classes designated should prepare detailed instructions for its own work, which, if approved by the Board of Surveys and Maps, should be published for general use. Each set of instructions should be complete in itself and should not refer to other sources for additional instructions. Fxamples of records and computations should be given for all operations.

Books of instruction for all classes of work should be furnished gratis to every technical school, college, and university that teaches engineering and should he supplied on request without charge to any interested engineer, in order to make the methods of work known to as many as possible and thus to aid in their adoption by States, counties, cities, corporations, and individuals. This will be of benefit to all concerned.

Arrangements should be made whereby any organization or individual who may wish to do control work of the first, second, or third order will be supplied by the Superintendent of Documents with field notebooks and record and computation forms at cost.

So far as practicable, the forms for records and computations used by Government surveying organizations in control surveys should be standardized.

It is just as essential to have the work of outside organizations and individuals standardized as it is to have control work by the Government bureaus standardized. The outside organizations and individuals have given very little attention to control surveys, and whatever standard specifications for control are adopted by the Government will undoubtedly be adopted to a large extent by others.

APPENDIX To Specifications for Horizontal and Vertical Control Defining Probable and Actual Errors

Approved April 13, 1926.

The “probable error” of the measurement of a physical quantity is obtained by mathematical formulas applied to the differences between the two or more measured values of a quantity and their mean value. The probable error is a measure of the accidental errors only - that is, of those small errors which have no marked tendency to be predominantly either plus or minus. The probable error is simply a measure of the closeness of agreement among the several values of a quantity obtained by successive measurements. It will give no indication of the presence of systematic errors - for example, if a steel tape graduated at 30° C. is used at O° C. and no temperature correction is applied, the measurements may agree within a very small limit and give a very small probable error, yet the result would be in error about 0.4 inch in every 100 feet or about one part in 3,000. Neither will the probable error give any indication of blunders, for a tape length dropped from each measure will not affect adversely the probable error of the measurement of a base.

The probable error of a measured base is found in the following manner. The base is measured in sections of about 1,000 meters each, and the probable error of each section is first obtained from the formula 0.6745√(Σv²/(n(n-1))) where v is a residual-that is, it is the difference between each measured length and the mean of all the measured lengths of a section-and n is the number of measures of the section. The Greek letter Σ indicates that the sum of the squares of the residuals (v²) is to be taken. If, as is usually the case, there are only two measures of a section, then the probable error of the section is 0.6745 times one-half the difference of the measured lengths of the section. The probable error of the entire base is expressed by:

p.e. = ±√(h₁² + h₂² + … + h_n²), where h₁, h₂, …h_n are the probable errors of the separate sections.

This and other formula relating to the several classes of errors may be found in many textbooks on geodesy and least squares.

The “actual error” is the difference between the true value and the measured value of a physical quantity. It is the sum of all the systematic and accidental errors which have not been eliminated from the final adopted measured value. As the absolute value cannot ever be known, the actual error cannot be exactly determined, but its maximum value can always be estimated. The accuracy of the estimation depends directly and entirely upon knowledge of the maximum uncorrected effect of each source of error.

To illustrate again by the measurement of a base, suppose that the error in marking and the error in correcting for temperature of the tape are the only ones affecting the measurement. The error in marking the ends of a tape is partly systematic and partly accidental; the systematic error will be eliminated by taking the mean of an equal number of forward or backward measures if the person marking remains always on the same side of the base line, and experiments show that with proper methods the accidental error in marking a single tape end is about 0.1 millimeter, or 1 part in 500,000. For a kilometer section of 20 tape lengths, the probable error from marking errors alone would be 1 part in √20 X 500,000 or 1 part in 2,235,000.

In correcting for temperature there are three principal component sources of error-namely, the error in the calibration of the thermometer, error in reading the thermometer, and the undetermined difference between the true thermometric reading and the mean temperature of the tape. Suppose standardizations and tests show that the probable error of calibration is half a degree centigrade and that the probable error of reading is of the same magnitude. Also, that the average difference between the true thermometric readings and the mean temperature of the tape under the conditions of measurement would not exceed 2°C. but that this difference is always of one sign. The probable divergence in temperature between the tape and the thermometer readings would therefore be 2°±√((0.5)2 + (0.5)2) and would certainly not exceed 3°. If the tape to be used were made of invar, with a coefficient of expansion of 1 part in 1,000,000 per degree centigrade, the maximum error to be expected would be 3 parts in 1,000,000, or 1 part in 333,000.

After the error to be expected from each source is evaluated an estimate can be made of the “total actual error,” which is one of the criteria for base measures.

National Geographic Society – Boston Museum of Science

A joint project under the direction of Bradford Washburn.

Final Report by Bradford Washburn, Director of the Museum

The first formal map of the Bright Angel area of the Grand Canyon was published in 1903 as a result of the extraordinary survey of 1902-03 by parties of the U. S. Geological Survey under the leadership of E. M. Douglas — with topography by François Matthes and control by H. L. Baldwin, Jr., and J. T. Stewart. This excellent “reconnaissance” map (scale 1:48,000, with 40-foot contours) was not materially improved until the new USGS Bright Angel Quadrangle (scale 1:62,500, with 80-foot contours) was published in 1960, by photogrammetric methods, from aerial photographs taken in 1954 and 1960.

Narrative

Why remap the Canyon?

I enjoy making maps. I was an instructor of cartography before I came to the Museum of Science in 1939 and I have tried to keep up with the great advances in cartographic techniques which have occurred in the last forty years — and whenever the opportunity arose I became involved in an interesting exploratory mapping project. In the fall of 1969 my wife and I visited the Grand Canyon and were disturbed by the fact that no large-scale maps of the area existed.

A map with a scale of an inch to a mile (1:62500) is simply inadequate to depict such incredibly rough country, with extremely intricate trails involving hundreds of tight switchbacks for use of either the hiker or the scientist who has any desire or need to know precisely where he is — or, indeed, precisely where he is going! This is also far too small a scale for the accurate plotting of the geology, botany or archaeology of this heavily-frequented and much-studied part of the Canyon.

After considerable research it became clear that neither the National Park Service nor the U.S. Geological Survey planned to remap the Canyon area on a larger scale, and I became intrigued with the idea of making a number of new sheets of the most intensely-used part of the Canyon on a manuscript scale of 1:4800 — a foot to a mile — with the long-range hope of eventually coalescing these large sheets into a single map on a scale partway between this and that of the small-scale government sheets.

Research and planning

Mrs. Washburn and I discussed this project with Harry R. Feldman of Boston, one of New England’s top professional surveyors, with whom we had worked before on the control of our large-scale maps of Squam Lake, New Hampshire and the Squam Range, and he expressed keen interest in working with us at the Canyon. The Museum of Science has owned a Wild T-3 theodolite for many years and Harry had just acquired a new Laser Ranger which appeared to be ideally suited to making precise distance-measurements over the incredibly rough Canyon terrain.

It was our plan to work together as volunteers, encouraging other volunteers to help us — and financing the project with any grants-in-aid that we could secure as the project progressed. Before plugging into a major commitment, we decided to visit the area once more, using a modest grant from my Museum of Science research fund, to try to feel the situation out — to see what the working conditions were, to investigate the availability and cost of reliable helicopter support and to actually make a few preliminary observations along and near the South Rim. We also speculated further by having vertical photographs taken of the entire area under consideration by Mark Hurd Aerial Surveys of Goleta, California. These were made with a Zeiss camera from an altitude of 16,000 ft. (sealevel) and flown both north-south and east-west in order to thoroughly cover every detail of the incredibly rough terrain.

We studied the existing maps thoroughly and secured all available control from the U.S. Coast & Geodetic Survey and U.S. Geological Survey. The area that interested us extended westward from Yaki Point eight miles to Hermit Creek, northward across the Canyon to Point Sublime and then eastward again to the vicinity of Bright Angel Lodge on the North Rim. This was a large area — well over one hundred square miles and it covered most of the “heart” of the Canyon which was then being visited by nearly three million tourists and hikers each year.

There was very little precisely-marked government control in this area – The USC & GS had first-order triangulation stations at Yaki Point (“Middle”) Point Sublime and Cape Royal. The positions of these stations were very accurate, but their altitudes were far less precisely known. The USGS had a triangulation station near Hopi Point (“Rowe”), another one (“Angel”) at the North Rim Ranger station and another at Obi Point. Rowe and Obi were easily accessible, but Angel lay amid huge trees, and a high tower would have been needed in order to observe from it. A very accurate line of levels had been run down the Bright Angel Trail to the Colorado River by François Matthes’ party in 1902 and a number of bench marks from this work still remained. Also, the National Park Service had done considerable additional leveling in the Inner Canyon and along ten miles of the lower course of Bright Angel Creek, in connection with the establishment of the water pipeline between Roaring Springs (on the North Kaibab Trail) and the South Rim complex.

What this all added up to was that all the control of the existing maps of this part of the Canyon depended on baseline measurements made in the desert many miles away, and that, except for a small number of widely-separated points, no reliable and marked control existed in our area of interest. We therefore decided to start the work with a clean sheet of white paper on which we marked the grid coordinates of Yaki Point (USC & GS station “Middle”) and Point Sublime (USC & GS station “Sublime”). We assumed these stations to be precisely positioned — and this of course yielded the azimuth between them. This azimuth was also checked in the field with theodolite work at “Middle” to USC & GS station “Royal” which lay east of our network.

We diverged for the only time in the whole project from our policy of an all-volunteer group of field workers in connection with doing precise leveling to establish a very solid datum for our project. To do this we hired Edward A. Krahmer of Sun Lakes, Arizona (highly recommended to us by the USGS) to run two level-loops for us from USC & GS bench-mark S-61 (6876.164 feet) at the head of the Santa Fe railroad yard at Grand Canyon Village. One of these closed loops ran out to Yaki Point and established the altitude of “Middle” as 7259.908 ft. The other ran out to Hopi Point, passing USGS station “Rowe” on the way, and set an altitude of 7042.953 feet at a new triangulation station which we set up at the tip of the point, in full view of the other great points along the central part of the South Rim: Yaki, Yavapai, and Pima; as well as virtually all of our key points on the North Rim and in the Canyon itself. Our entire map was to be hung on the positions of Middle and Sublime, the azimuth of the line between them and the altitudes brought to “Middle” and Hopi from S-61. Mr. Krahmer also swung past a new station which we set on the roof of Yavapai Museum (firmly related to its stone foundation) and gave it an altitude of 7082.225 ft. Also accepted as vertical control down in the Canyon were those of Matthes’ 1902 bench-marks related to the Bright Angel Trail, and all of the National Park Service level stations between Roaring Springs and Indian Gardens.

We are extremely grateful for all of the assistance given to us in this regard by the USC & GS, the USGS and the Park Service — and for five years of continuous help and advice given to us by Robert Lovegren and Merle Stitt, the superintendents of Grand Canyon National Park, and a score of the members of their staff without whose advice and counsel our work would have been quite impossible.

Initial contact

Our first trip to the Canyon was made in 1971 (Feb. 17-28) before we had developed solid plans for the project — partly to appraise the whole situation, and partly to actually start some of the work if conditions looked favorable and Park Service interest in what we hoped to do appeared high. Those in our tiny party were Mrs. Washburn and I, plus our daughter Betsy (who lived in Denver) and Wendell Mason of Boston, a longtime friend, professional surveyor, and Harry Feldman’s chief assistant.

This first trip was extremely successful. We experienced the usual incredibly fine Canyon weather (a pleasant change from the myriad weather problems encountered working in Alaska and the Yukon). We established solid relations with the Park Service; we located all of the key survey stations on the South Rim described in the lists given to us by the government; and we also set up a number of our own new stations both along the South Rim and somewhat out into the Canyon. We also set up a good working relationship with Grand Canyon Helicopters who performed most of our support for the first three years in the field. Late winter is an excellent time to work at the Canyon and we accomplished a great deal, despite the fact that we were in the field for only 10 days. Needless to say, because we were all busily employed on other major jobs and doing this “on the side,” it was clear from the start that it would take us a long time to reach our goal, a tiny bite on each trip, but we enjoyed it this way and we rapidly developed a delightful spirit of camaraderie between the two of us who were “regulars” on each trip and the many volunteers who worked so enthusiastically with us.

After the first trip, we reviewed progress and were very pleased. We had only spent $2400, had already set up a very sound composite base along the South Rim (Yaki-Yavapai-Hopi-Pima) and had used the helicopter and laser enough to be certain that they were the basic tools needed for our success. However, the laser instrument (Laser Ranger II) was not powerful enough to measure distances over five miles long, and we needed something with much more range to develop a sound network across to the other side of the Canyon — several of the sights that we needed ranging between seven and thirteen miles.

So we contacted Laser Systems and Electronics of Tullahoma, Tennessee, which had made Harry’s Ranger II, and asked for their help. Out of this telephone call developed a working relationship that has been of extraordinary importance, not only to this Grand Canyon project but also to our subsequent work both in Alaska and New Hampshire. Our second trip was planned for almost a full month (June 16 – July 11, 1971) and this time our volunteer ranks were expanded to include not only Wendell Mason but Harry Feldman as well as Buddy Cutshaw and Wayne McQueen of Laser Systems — to field test a new Laser instrument which was under development at the time.

It would take many, many pages of intricate text to cover the day-to-day work of each of these trips, all of which, of course, is recorded in our logs of the project. This account will simply deal with the basic steps of progress as we went forward and will recount the principal techniques used in our work.

Developing a survey network

For the second time, we invested very little of our time down in the Canyon, but concentrated on measuring the long lines so essential to the development of a strong overall survey network and some of these reached significantly beyond the limits that we had first set for our project. We continued to add to the control out in the Canyon by measurements to and from Zoroaster, Cheops, Set and Ra — all points that rose dramatically above the Canyon floor, yet were easily accessible by helicopter.

Each of our survey stations consisted of a one-inch hole, three inches deep, drilled in the rock, using a Black and Decker Rotohammer, operated by current supplied by a Homelite generator — both contributed to our project by the manufacturers. This gear was hauled by helicopter to almost all of our stations, but a half-dozen holes were cut by using an old-fashioned hand-drill and sledge-hammer.

When the hole was completed, we drove into it a 3″ x 3/4″ galvanized pipe nipple, then added a coupling and a section of pipe, varying in length from 2 ft. to 5 ft., to which we attached our targets (see illustration). Those which we had to see from a number of different directions were 16″ plastic spheres (National Geographic world globe cores!). Those which were to be sighted from only one direction were simply rectangular-plywood targets bolted to the iron pipes. All were painted flat white, then spray-painted with fluorescent orange, which appeared to be the most practical color for visibility against the complex Canyon backgrounds. Repainting was necessary about twice each year, as the paint rapidly faded in the intense desert sunlight.

As our stations were established, they were marked with large white cloth targets staked out on the ground, and photographed from the air at low altitude, so that they could be precisely related to our 1970 high-altitude photography. This was obviously not the normal way to mark control — which should all have been targeted in advance and photographed before field-measurements started — but this orderly procedure could not be followed on an informal project such as ours, inching slowly forward, with exceedingly limited finances as well as a tiny contingent of personnel.

At the conclusion of the two trips in 1971, all of our vacation time was exhausted and we retreated to Boston to sum up the results of our work. We had spent, in all, 26 days in the field, had made 85 helicopter landings. We were now sure that what we were doing made sense. Our preliminary calculations were yielding excellent results. Our trusted Wild T-3 theodolite was working perfectly and the two Laser Rangers had made distance measurements speedy and simple. But it was clear that, unless we wanted to whittle away gently on our project for years, we would need much more financial assistance than my small Museum research fund could provide — particularly because a great deal more helicopter work lay ahead, as we worked further and further away from the South Rim — and we had not yet even started the costly phase of photogrammetric control-proliferation and contouring.

Accordingly, in the fall of 1971, we approached the National Geographic Society to see if we could enter into a collaborative arrangement with its Committee for Research and Exploration to split our future expenses equally between the Museum and the Society. This first proposal envisaged a map that would cover 84 square miles, 10.5 miles E-W and 8 miles N-S, stretching from the South Rim to a point approximately 3-1/2 miles miles north of the Colorado River. To our delight, this proposal was accepted by the Society on December 10, 1971, and the remapping of what we called the “Heart of the Grand Canyon” became a formal reality.

Extending the area to be mapped

Our third trip (February 18 – March 5, 1972) continued and expanded our station-marking and angular measurements in the southern half of our area and started detailed mapping of the trails, with work on the Bright Angel, Hermit and Waldron, assisted by our longtime friend Jack Pechman of Denver. No laser work was done on this trip.

As we became more familiar with the area, it also became more and more apparent that, although much more fieldwork would be involved, it would make no sense to have our northern limit so far short of the North Rim. So we reapproached the National Geographic about the advisability of extending our work one mile further northward, to encompass Ribbon Falls, Shiva and Buddha Temples. This enlargement of the project was approved by the Society on June 8, 1972.

This increased the size of the area to be mapped by 10.5 square miles (total now 94.5 square miles) and we arranged to have an additional strip of E-W aerial photos made to cover this new area.

While this field work was progressing, Lockwood Mapping was at work contouring the parts of our map on which the control had been completed. This work was done at a scale of 1:4800, between March and July 1972 — scribing the 50-ft. contours directly from a Wild A-7 plotter onto plastic “scribecoat” sheets, thus avoiding the loss of detail and quality inevitable when contours are first marked in pencil, then later scribed onto the final manuscript by another draftsman.

Laser and theodolite work

Our fourth trip involved a great deal of activity with both laser and theodolite. In addition to Wendell Mason, Buddy Cutshaw rejoined us with a very powerful new instrument, the Rangemaster, with which, for the first time, we were able to make the long sights between Yavapai and Bright Angel points (10 miles) and from Yaki Point to Point Sublime (13.5 miles). Our work afoot on the trails intensified, and was done whenever we had windy days which made helicopter work impractical. Throughout 1972, now working with nearby Landis Aerial Surveys of Phoenix, we completed a complex series of low-altitude (8500 ft.) vertical stereo-photo-strips along the trails, as it was impossible to secure the desired detail in them from 16,000-foot photography.

Although a considerable amount of control still remained to be added (as well as a massive amount of trailwork) the early summer trip in 1972 essentially broke the back of the overall project. We were now thoroughly familiar with the area and how to work in it. We had a top notch group of volunteers, and the helicopter pilots, led by Dan Nicholson, had now become expert at the demanding sort of pinnacle-landing work that was essential to our project.

Level lines and young benchmark hunters

In late August and early September 1972, Trip No. 5 (Aug. 30-Sept. 18) took a tremendous slice out of our agenda. Ed Krahmer carried out a line of levels for us along a three-mile section of woodroad northward from Tiyo Point, thus giving us strong vertical control across the middle of the wooded North Rim plateau. This level-line also had a strong start, as our figures and those of the USGS for the altitude of Tiyo Point agreed within a foot. This simply reconfirmed what repeatedly had happened to date: wherever we zeroed in on a precise spot which was also in the USGS survey, our figures and theirs virtually coincided — the big difference between our maps lay in the enormous detail that our low-altitude photography and large-scale contouring yielded — and this was the reason for our work. In addition, because of this large scale we were forced to add an enormous amount more control spread throughout the area.

We completed all of our observations in the new northern extension on this trip and also made a precise large-scale survey of the tree-covered area around Indian Gardens. Harry Feldman and Wendy Mason helped us throughout this period, and Dick Hinderlie and Margo Sweet assisted by making a large number of distance-measurements along the trails. And one of the most delightful high-points of the whole project was the discovery of an ancient bench mark on the Bright Angel that had been “lost” for many years — by Ranger Gary Howe’s two young sons Rusty (age 11) and Ronnie (age 9)! We told them more or less where they had to search, offered a $10 reward for finding it — and their sharp young eyes, coupled with a lot of patient scrambling among rocks and bushes, won the prize!

Another expansion of the project

As the fall of 1972 deepened, great progress had been made, and on October 30 we sent the first nine sheets of our manuscript to the National Geographic, covering 94.35 square miles — complete topographically, but still missing a substantial amount of trail-detail. This photogrammetric work was done by Lockwood Mapping, Inc. of Rochester, New York under the direction of Ray Byrne and Keith Adams.

When we forwarded these sheets to the National Geographic, we recommended one more major addition to the map: to extend it another 3.88 miles further northward, to take in the whole southern edge of the forested North Rim plateau, as well as the Grand Canyon Lodge and the NPS North Rim Ranger Station. While this proposal was under consideration, a pleasant bolt of lightning struck!

Conrad Wirth, the eminent past director of the National Park Service, was a member of the National Geographic’s Board of Trustees. While the Board was considering our proposed addition, he not only spoke in favor of it but also recommended that we also add a strip all along the eastern edge of the map in order to include most of Bright Angel Creek and all of the course of the North Kaibab and Clear Creek Trails. Although this meant extending our work for at least another year, we were delighted at this proposal — which was favorably approved by the National Geographic on December 20, 1972. This added 70.24 square miles to our map, bringing the grand total to 164.602 square miles.

With the completion of the first nine of the large-scale sheets involved in the original survey plan, it was very exciting to see the end-result of all of our labors in the field beginning to take the sort of shape we’d dreamed about. We now prepared a battle-plan for completing the entire twice-expanded project: Four more sheets were needed to complete the first expansion to the North Rim. Then four more were required to cover Mr. Wirth’s eastern edge. Trip Number 5 (August 31 – September 16, 1972) yielded the control still needed to contour the entire North Rim area and Lockwood proceeded with work on these four sheets in the spring and summer of 1973.

In the midst of this activity, the National Park Service decided that a new very-large-scale map of the South Rim Headquarters area was needed. Low-altitude pictures of this had already been flown by Hurd, so we provided the needed laser- control and it too was contoured by Lockwood Mapping during the period April – November 1973 at U.S. Government expense. This proved extremely valuable from our standpoint, as it yielded a very detailed up-to-date map of a very intricate part of our sheet and we were glad to contribute our control-work for it in order to speed its completion.

Work by helicopter and on foot

In fact 1973 was the busiest year of the whole project. Three trips were made to the Canyon. Trip No. 6 (March 22 – April 2) closely followed a helicopter flight by Dick Hinderlie and Dan Nicholson on February 24th to drill and target six of the new stations required to control the central part of the eastern addition. Heavy snows of course prevented effective work on either rim at that time of year. Mrs. Washburn and I and Wendell Mason joined Dick for two intensive weeks of late winter helicopter-and-laser work that nailed down our needs in the dramatic region of the Ottoman Amphitheatre, Howlands Butte, and Zoroaster Canyon. Then we returned in the early summer of 1973 for Trip No. 7 (June 12 – July 8) to complete both the northern and southern ends of the eastern edge, after the snows had melted and foot-travel again became easy on the rims.

During this period of intense activity in the field, additional volunteers were very important to us, particularly on the North Rim, and not only Harry Feldman joined us to help with many key laser-sights, but Dick Hinderlie, Fred Eidsness and Lindsey Happel worked for scores of hours with us on this most complex and difficult part of the whole map — because steep slopes and dense forest made it impossible for us to use helicopters, and most of our final stations had to be marked, drilled and occupied afoot. We also reconnoitered the entire 14-mile length of the North Kalbab Trail and started the seemingly-endless task of marking accurately on our low-altitude aerial photographs the parts of the trail that were concealed by trees or deep shadows. Dan Nicholson, our close friend and leader of most of our helicopter-flying up to this point, had left to teach helicopter pilots in Iran early in the summer of 1973 and shortly after this Jerry McMullin, an equally competent pilot from Madison Aviation, took over the bulk of flying for us.

Our eighth trip was the shortest of all — only four days (October 21-24, 1973). I had a lecture in Seattle and returned to Boston via the Canyon, meeting Mrs. Washburn there for an intensive attack on the complex details of the upper five miles of the North Kaibab, before the winter snows engulfed them. David Ochsner, NPS ranger and gifted photographer, accompanied us on this trip. Of all of our many forays to the Canyon, this was the most beautiful — with the brilliant blue skies of fall, chilly nights, thrilling stars and the aspens in all their autumn splendor.

As the fall of 1973 progressed, Lockwood’s photogrammetrists were busily engaged in plotting the contours of our last sheets. Sheet 13, covering Bright Angel Point and the North Rim headquarters area, was completed on September 24 and work then progressed southward along the eastern edge of the map, till sheet 17 was finished on January 8, 1974. As these sheets arrived in Boston, one by one, they had to be meticulously checked for accuracy of detail. Long sections of the trails were still incomplete, although the drainage, topography and buildings were essentially finished by early 1974.

Intense field work, and an inspiration

Trip No. 9 from February 20 – March 5, 1974 dealt almost entirely with the trails, and we did scores of miles of walking along the Bright Angel, Tonto, River, North Angel and Clear Creek trails — long segments of which were invisible on our vertical pictures, either because they were obscured by shadows or because they were so infrequently traveled that there were not the slightest traces of them on even the low-altitude pictures. We had found on two past trips that late February and early March is a perfect time for work in the depths of the Canyon and this one simply reinforced that conviction. And we had new and congenial hiking companions in Charlie Hovey and his son from Boston — and Ron and Ann Merritt of Russell, Massachusetts.

Whenever possible, we tried to tie our Canyon trips to other necessary Museum activities on the West coast which would reduce our travel costs and stretch our budget-dollars. On July 25, 1974 we returned to the South Rim en route to Boston from Alaska — and stayed through July 29th — Trip No. 10. These were four extremely intensive days of work: out to Widforss Point and back to detail this 5-mile trail afoot and under a broiling sun; then over to Uncle Jim Point and back to finalize the invisible parts of this little-traveled North Rim path; then slowly and meticulously down the upper five-miles of the North Kaibab Trail to check its final manuscript; then down the Bright Angel to check the intricate contortions of its upper 4-1/2 miles — as far as Indian Gardens.

It was two miles down the Bright Angel on this beautiful final morning (July 29, 1974) that we had the most exciting moment of our whole project. As we rounded a sharp curve, we came upon two young men walking up the trail hand-in-hand. One asked me what we were doing and how our measuring wheel worked. His companion expressed avid interest and said that a good map would have made their trip more interesting. Then his friend turned to him and said, “Joe, how’d you like to feel it?” It was not till then that we realized that Joe was totally blind! I led his deft fingers to the wheel, its spokes, the Veeder-counter and the tiny “tripper” which logs off each foot of distance. We chatted for a few minutes about accurate maps and how helpful they are to hikers. Then we said goodbye and they headed briskly off up the trail beneath the searing summer sun. As we resumed our descent, our hearts welled with respect for that brave young fellow and his generous guide — on an adventure that will never be forgotten — either by them, or by us!

The map production process

As 1975 arrived, our work was drawing to a close. We had already made ten trips to the Canyon and spent 122 days in the field. We made our last winter trip (No. 11) from February 22 to March 1 and focused it on introducing Paul Witzler to the Canyon. He had flown there from Berne, Switzerland, where he worked at the Landestopographie, Switzerland’s Federal Topographical Survey. Paul was the world’s top expert on shaded relief — the subtle shadows that give a three-dimensional feel to a flat map. He spent two weeks at the Canyon as our guest, studying its shapes and colors, and made important recommendations to us later about the colors needed to depict the Canyon’s savage relief most effectively on our new map. One day we walked the entire nine-mile length of the Clear Creek Trail, checking every detail of it in our final manuscript. Another we completed the lower half of the Bright Angel — five hours to do 3-1/2 miles. Then down the lower two-thirds of the steep Hermit Trail, completing it too, all the way to the Colorado River. When we left, Paul had developed a marvelous understanding of the terrain, both from the air and on the ground — and the end of our work was just around the corner.

Our final trip (Number 12) was from June 28 to July 6, 1975: Two weeks of picking up loose ends; very low-altitude aerial photography of a number of intricate spots on the trails; and final coordination and farewells to all the volunteers of the Park Service who had helped us so much during the last four eventful years.

Although the public has always had the illusion that one moves directly from work in the field to the printing press in map production, a long, complex frustrating interval always lies between these two extremes. The Grand Canyon map was no exception to this rule. Up to this point, the Museum and the Society had shared the expense equally. From now on to the end, this map was entirely a National Geographic project.

Four steps still remained: The final coalescing of all of Lockwood’s 17 sheets of contouring into a single sheet at 1:24,000 (one-fifth the original scale); the completion of the large-scale maps of the trails and their reduction and integration into the final manuscript; the lengthy work of cliff-drawing; and, finally, the equally time-consuming and demanding task of drawing the shaded relief.

During the final phases of our field work, Raytheon-Autometrics of Sudbury, Massachusetts had been preparing strip-maps of the trails at twice the scale of the 17 manuscript sheets — 1:2400. These strips were made of the Bright Angel, the South Kaibab, the Hermit, the North Kaibab and the lengthy Tonto Trail. The detail-work on these trails sheets consumed a large part of our final weeks in the field. An immense amount of work had to be done on foot checking details and, as mentioned before, filling in scores of gaps caused by shadows and trees and in areas where the terrain was so bare and rocky that the paths were invisible even in enlargements of the low-altitude photographs. It was not until April 23, 1976 that I had completed the drafting of the last of these trail-sheets which were done on my own drafting table in Belmont. This was slow, meticulous, fascinating work and I enjoyed it immensely. Without this accurate detail it would be impossible for a hiker to find his exact position on these wonderful trails — and this was one of the main objectives of our whole project. Later on it is our plan to publish very-large-scale strip-maps of at least two of the most important of the trails, but that will be another story.

While this last field work was going on, the final contours and drainage were being scribed at the National Geographic, by Norbert and Walter Vasques, and Thomas Gray was working on intricate problems of nomenclature and compilation of all this data.

The cliff-drawing was executed for us by Rudi Dauwalder and Alois Flury at the Swiss Federal Institute of Topography in Berne during the period from July 23, 1976 to February 1, 1977. A map of the Grand Canyon without considerable use of cliff-hachures would involve a huge amount of meaningless concentrations of brown ink where dozens of parallel contours were jammed together on the steep slopes — and, far worse, in areas where hundreds of feet of utterly vertical cliffs were encountered. Dauwalder and his associates were the top people in the world in this exacting frontier between art and science and they did the work superbly — often investing more than a day of intense labor to produce a few square centimeters of cliffs. The illustrations clearly show how a typical cliff-drawing problem was handled on the slopes of Isis Temple. The only drawback of this technique from the standpoint of pure science is that in areas where cliffs are really perpendicular (or overhanging) there is no “room” to do the hachuring, and some “artistic license” must be taken in “stealing” a bit of space for this purpose from the slope immediately above and below the cliff.

This work was all done on a scale of 1: 24,000, a huge reduction of the 17 original sheets, coalesced into a single manuscript 33″ x 34″. If our scale had been larger, the sheet would have been hopelessly unwieldy for use in the field — or we would have had to resort to two sheets. If it had been smaller, we would have sacrificed most of the fine detail that was, after all, the basic objective of the whole project.

Dauwalder’s work was done on four small sheets which were fitted together and sent to Washington in February, 1977. There expert craftsmen at the National Geographic’s Department of Cartography coordinated them with the contour-manuscript, meticulously removing the thousands of crammed contours whenever they were replaced by cliff-drawing (see illustration).

Then another full year of tremendously demanding artwork followed, as National Geographic artist Tibor Toth, trained a dozen years ago by Swiss expert Paul Ulmer, carried out the relief-shading (October 21, 1976 – September 7, 1977). Unlike the cliff-drawing which is cut in a manuscript emulsion by a sharp scribing tool, shaded relief is produced by employing both the airbrush and a variety of pencils of differing degrees of hardness.

Final coordination and publication

Although I enjoyed the thrill of coordinating this work by mail, telephone and occasional on-the-spot conferences in Washington and Berne, the great basic burden of managing the many stages of this lengthy and intricate process fell on the able shoulders of Bill Peele, the National Geographic’s chief cartographer — who tragically had a severe heart attack on August 10, 1977 right at the peak of the activity. His assistant, Richard Rogers, carried the burden superbly in an anguishing interregnum before Richard Darley succeeded as the new chief cartographer September 11, 1978.

In the late fall of 1977, the editors decided that the map would be published as an insert in the July 1978 National Geographic Magazine — and the next eight months saw a veritable tempest of cartographic activity: final coordination of the contours, drainage, cliffs, shadows and trails; addition of titles and nomenclature after the most careful checking with local experts of the National Park Service and Professor Harvey Butchart, the clearly-acknowledged authority on the location of reliable springs, place-names and other essential details.

Finally the new map of the Heart of the Grand Canyon went to press on May 4, 1978. It was printed in six different colors by R. R. Donnelley & Sons Co. — 10,400,000 copies on 1,100,000 pounds of paper, using almost exactly 17 tons of printers ink! This edition, which appeared in the National Geographic Magazine for July 1978, as planned, had to be considerably narrower than the full area that we had mapped, as the full size (east and west) would not fit onto the “web presses” needed to print an edition of this size. Later, in June, a separate edition of 34,500 sheets was printed on waterproof paper by Lebanon Valley Offset Co. with the full 33″ x 34″ size — appended to this report and for sale at the National Geographic Society, the Grand Canyon and the Museum of Science.

This project accomplished substantially more than simply the production of a new 1:24,000 map of the central part of the Canyon. In the long run, the 17 manuscript sheets which were reduced and coalesced to make this medium-scale composite map of the area may have more value than the 1:24,000 sheet — as they contain a vast wealth of fine detail (even individual rocks, trees, bushes and tiny undulations of the footpaths) that could not possibly be reduced to a smaller scale than 1:4800.

This detail could easily have been omitted from the master manuscripts at a considerable saving in cost. However, their production on this scale and with this fine detail was a basic part of this project, which, in addition to yielding the 1: 24,000 sheet for hikers, campers and tourists, envisaged substantial professional value in these large-scale manuscripts for use by geologists, botanists, archaeologists and other scientists for precise plotting of their field work in years to come.

Viewing and obtaining the maps

These sheets were meticulously studied and revised during 1979. The scribed manuscripts, completed on November 12, 1979, are now stored at the Cartography Department of the National Geographic Society in Washington. One set of cronaflex positive prints is there and a second is kept at the Museum of Science in Boston. Copies of these sheets may be purchased at cost from the Museum by those wishing to pursue serious scientific studies in the field.

Two similar manuscript sheets covering the complex and extremely precipitous Inner Canyon area on a scale of 1:2400 were prepared by Swissair Photo & Vermessungen in Zurich during 1975-76. These maps are also available at the Museum of Science — not the National Geographic.

Finally, pencil manuscripts by Raytheon/Autometrics of the five famous trails (Bright Angel, Hermit, North and South Kaibab and Rim) on a scale of 1:2400 are filed and available for reference at the Museum of Science. These large-scale manuscripts and those of the Inner Canyon were used in conjunction with the 1:4800 sheets to assure maximum possible accuracy of the trails, and they are certain to prove very useful to those doing any sort of field work along the trails that requires a precise knowledge of position.

In conclusion, I wish to express the utmost gratitude to the National Geographic Society and my Museum without whose full and generous support we could never have attempted this project — and to the scores of volunteers, recorded elsewhere, whose enthusiastic and selfless cooperation made the field work successful. I doubt whether a surveying project of this scope and complexity has ever before been attempted by an all-volunteer group.

And lastly, I cannot close without expressing my admiration for the extraordinary work of the topographers who preceded us at the Canyon over a period of almost exactly 100 years. What they produced working afoot and on horseback with plane tables and transits instead of theodolites, lasers and helicopters was, of course, one of the greatest accomplishments in all topographic history. It was a thrill and a privilege to travel in their footsteps in this epicenter of our world’s most awe-inspiring scenery.

Technical Notes on the Survey Program

The resurvey of the heartland of the Grand Canyon 1971-1975 was based on two USC & GS survey stations on the North Rim Of the Canyon (Sublime and Obi), one USGS station (Rowe) and one USC & GS station (Middle) on the South Rim — also USC & GS Bench Mark S-61 on the South Rim. Leveling of the USGS along the Bright Angel Trail was used as datum along this trail, as was National Park Service leveling along the lower ten miles of the North Kaibab Trail.

In all, 92 survey stations were used in this new network. Seventy-five of these were positioned by both theodolite and laser observations (see list). Two were unoccupied intersected points; 8 were targeted intersected points; and three were positioned by existing US government coordinates. The azimuth from “Middle” (at Yaki Point) to “Point Sublime” (both USC & GS stations) was assumed as the basic direction on which all others were hung. This direction was also checked by observations at Middle to USC & GS station “Royal” at the southeastern tip of the North Rim, well outside the area being mapped.

Horizontal and vertical angles were measured with a Wild T-3 theodolite. Slope distances were measured with a Laser Ranger II, a Ranger III, and a Rangemaster I, loaned to the project by Laser Systems and Electronics Inc. of Tullahoma, Tennessee, now a division of Keuffel & Esser, Inc. Although most stations were occupied by both theodolite and laser, a small number were not instrument-stations and positioned by intersection of targets set up on them in advance. Two stations (Isis and Osiris) were intersected and not occupied at all.

The helium-neon laser of the Rangers that were used was modulated by a crystal-controlled, electro-optical cell and directed onto an array of retro-prisms positioned at the point to which the distance measurement was to be made. The reflected beam returned from the prisms to the Ranger which is both a transmitter and receiver. Here the light-beam is converted into an electrical signal. The transmitted and reflected beams are compared by the instrument’s self-contained computer which performs a succession of “phase-comparison” measurements, averages them and then converts the result into a direct digital distance readout either in hundreds of a foot or millimeters, as desired.

One problem related to the precision of these distance-measurements remains unresolved, though of little practical importance, because of the relatively short lengths of the lines: This arose from the fact that all “parts-per-million” corrections fed into the Ranger’s computer were based on the average barometric pressures and temperatures, taken at both ends of the line at the time of measurement. Without the costly use of a helicopter to fly a thermometer along the line at the time the measurement is being made, it is clearly impossible to ascertain the true average temperature of the air-mass out in mid-air between the Canyon’s pinnacles.

The stations in the network (see diagram) were distributed as evenly as possible over the area to be mapped, except in the area of the heavily-forested North Rim plateau. However, vertical control was brought into the center of this area by leveling northward up a woodroad from Tiyo Point. The positions and altitudes of four points on the South Rim (Yaki, Yavapai, Hopi, and Pima) precisely linked by both laser and theodolite, anchored near the center on USGS “Rowe” and on the east at USC & GS first order station “Middle” provided a “composite base” for the network. All points out in the Canyon and along its opposite rim were linked by triangulation or trilateration to this South Rim axis, with checks to “Sublime” (slightly beyond the West edge of the map) to the west and “Obi” to the east on the North Rim.

All computations were carried out on the Arizona State Grid System. The laser slope-distances were first reduced to the horizontal and then to sea level and finally to the grid system. Horizontal angles, as measured in the field, were used directly in the grid computations, without change. The theoretical difference between field angles and grid angles was less than one arc/sec and was therefore ignored.

Elevations were based on the altitudes of Yaki and Hopi, tied by closed, precise level-loops to USC & GS Bench Mark S-61 (6876.164 ft.) at the head of the Santa Fe railroad tracks on the South Rim. All other elevations were computed from vertical angles and horizontal distances, the great majority of which were slope-corrected laser-distances. In many cases, reciprocal vertical angles were observed, which gave additional strength to the station involved. It is our belief that all altitudes are accurate within 0.2 foot. Many are within 0.1 foot. Geographical positions are probably accurate to within 0.10 foot. The appended Control Diagram makes clear the distribution of the survey stations and the method used to fix the position of each. Many of these stations were in essence trilaterated and the horizontal angles used for checking only. Tables of Altitudes, Geographical Positions and Laser Data are also appended for reference purposes.

Since this work was completed, a controversy has arisen with regard to the altitude of Bench Mark S-61. This has not yet been resolved, but, if an error does indeed exist at this station as alleged, all altitudes on this map must be adjusted upward by approximately two feet.

Photogrammetric Notes

The photography used to produce this map was on a scale of 1:24,000, using a Zeiss RMK-A-15/23 camera No. 21220, 152.46 mm focal length. The pictures for the basic 13 sheets were made by Mark Hurd Aerial Surveys of Goleta, California. The photographs for the four sheets along the eastern edge were made by Landis Aerial Surveys of Phoenix, Arizona, using a Zeiss RMK-A-l5/23 camera No. 21178, 152.57mm focal length. These two contractors roughly split the low-altitude photography at 12,000 ft. and 8500 ft. used by Raytheon-Autometrics to map the trails. Lockwood Mapping, Inc. of Rochester, New York did the overall photogrammetry and the 1:2400 contouring of the Inner Canyon area was done by Swissair Photo & Vermessungen of Zurich.

Vertical relief was depicted by 50-foot contours, supplemented by 25-foot contours in the gentler gradients of the rims and the Tonto plateau. The computation of the field data was done by Harry R. Feldman, Inc. of Boston, Mass. using coordinates based on the Arizona Grid datum. The horizontal and vertical photogrammetric model control was achieved through a semi-analystical triangulation program for both the vertical and horizontal solution.

Compilation utilized a Wild A-7 Autograph on which the pencil chuck of the plotting table was replaced by a scribe-point. K & E scribecoat material was used as the compilation base. By use of direct scribing without the intermediate pencil step, a much more accurate reproduction of the character of the terrain was possible.

A number of unusual problems were encountered and procedures to deal with them were developed which will be helpful in facing similar mapping in the future. Often the operators would lose stereo-vision while contouring the high vertical cliffs and had to back up and start the contour-line over again. Deep shadows, even at noon, on the north sides of the vertigenous cliffs made contouring of these areas difficult — and trails were often completely invisible where they passed through these shadows.

The plotting of the trails and drainage were done on different sheets from the contours. This was essential in this unusual project and it resulted in a number of special problems. In many areas because of the bare, and terrain, there were a multitude of drainage-courses, which would have seriously cluttered the sheets if they had all been depicted. The selection of the key courses was often very difficult. Then, when plotting the trails and drainage, the slope was often dropping so rapidly that it was very difficult to synchronize and maintain a precise Z-position, correctly coordinated with an equally-accurate X and Y position. This problem often resulted in a slight lateral shift in the location of the planimetry, which later had to he corrected to fit the contours in the final manuscript which coalesced both sheets. Normally these problems would have been easily controlled on a single penciled manuscript sheet, simultaneously involving drainage, contours and trails.

We owe a special debt of gratitude to Ray Byrne and Keith Adams of Lockwood, John Baber of Raytheon-Autometrics and Werner Altherr of Swissair Photo — and to all of their skilled associates who actually did this intricate and painstaking work.

Sources of survey data

This list contains both professional data and information for recreational hunters, so please note the source of each and evaluate accordingly. Also note that some sources, USGS datasheets in particular, contain many superseded marks that are no longer reliable for survey purposes but are very useful for recreational survey mark hunting.

Professional resources

NGS Database: Datasheets and Survey Mark Recovery: Search/browse the main authoritative source of official survey data for the United States.
USGS Datasheets: USGS datasheets I have obtained and scanned. USGS does not offer digitized datasheets.

Survey Mark Hunting

Sun, 16 Aug 2026 21:31:00 -0400

NGS Triangulation Station BEAUTIFUL

Survey marks or monuments are objects used to mark a precise location and/or elevation on the earth. Survey mark hunting, sometimes referred to as “benchmark hunting” regardless of the type of marker being sought, is simply the activity of searching for these survey marks. When we find, or “recover,” a mark, we do not take it or disturb it in any way. We document the mark’s condition and make note of any updates to the description and geographic coordinates that we think are needed. Then, when applicable, we send our report to the National Geodetic Survey (NGS) or the U. S. Geological Survey (USGS).

NGS Survey Mark FAQ: NGS provides answers to some basic questions about survey marks and datasheets.
USGS Guide to Land Survey Benchmarks: USGS has a guide to basic information about survey marks and how to find them.
Standard Numbered Notes for Description of Marks: This excerpt from The Manual of Geodetic Triangulation is useful when you’re out in the field and the mark descriptions refer to Note 4, Note 11, etc.
Joy of Geodetics: For a very deep dive, The United States Power Squadrons have provided a series of presentations to instruct members on methods of surveying, types of markers, and procedures for reporting recoveries.
