  • Official PA Dept. of Highways Description:


Rich and I spent a fantastic morning in Montrose finishing up the third annual Architectural Treasure Hunt. After turning in our clue sheets, stopping for some chocolates and having lunch, we drove back home by way of Route 29. Along the way, it occurred to me that there was a new geocache near Lake Carey, so we took a short detour to search for it. We didn't find the cache, but we did find this old PDH disk on the bridge nearby. It's stamped with a new PennDOT number. It appears to be in good condition and quite stable.

  • Is there a database for the PDH markers? I find them all the time while out caching but have never found anywhere online where the info can be accessed.

    • I have not found anything specifically for PDH markers. The only site with any PennDOT data that I’ve found is PennDOT PAMS (Photogrammetry Asset Management System) and it is woefully sparse.

      If you want to check it out, note that the green markers are PennDOT survey points. If you click “Identify Query” and then click on an area of the map, you’ll see datasheets for the nearby marks appear in a frame at the bottom of the page. Clicking on the datasheet icon will bring up the PDF.

      Good luck, and please let me know if you discover anything else!
