Finding RHONDA

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.

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!

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.

“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!

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.”

Jack has also submitted some photos of the site of beacon #42 from different vantage points. He writes: “The arrow points east (towards Omaha, of course). Easily seen once you walk a dozen yards off the road. Tail, square tower pad and arrow head are all present and complete.”

Thank you for your contributions, Jack!

Government Shutdown: Services Unavailable

Due to the government shutdown, the NGS website and many USGS services are currently unavailable.

Archived NGS datasheets (from 2000-2001) are available at Geocaching.com: https://www.geocaching.com/mark/

These are useful only for benchmark hunters and are not to be considered reliable survey data.

Maryland USGS Datasheets Posted!

Jeff Jalbrzikowski of NGS was kind enough to send me the full run of scanned USGS datasheets (15′ topo quads) for Kentucky, Maryland, West Virginia, Ohio, Pennsylvania, and New York. It was such a treat!

I have a few of the states nearly ready to go, and Maryland is complete.

Thank you so much, Jeff, for reaching out and providing me with this fascinating historical data!

Arrow at Great Salt Lake, UT

David Izatt has submitted the following photos of an arrow at the site of SAN FRANCISCO—SALT LAKE AIRWAY BEACON 59 (the beacon is now destroyed).

Dave writes: “This arrow has also been recently painted with orange paint. I do not know the story behind this. The arrow is on the south side of the Great Salt Lake. It can be accessed from the dugway exit on Interstate 80. The road is gravel and dirt. Most vehicles should have no problem. Coordinates are: 40.7500160°,-112.6482090°.”

As always, thanks for your contribution!
