I was staying in Troy this weekend and decided to search for a few local benchmarks. This one seemed like a likely candidate. I started out very early in the morning and located the abandoned railroad bed with no trouble. But the only landmark mentioned was a stone foundation I couldn't find; I knew better than to depend much on the coordinates; and the vegetation in the area was so thick (and sharp!) I didn't think I had much of a chance of seeing or getting near the mark. I walked up the railroad bed for some time and, not finding anything of interest or even a likely starting point, turned around and headed back. It was then that through the thorns and branches I spotted what looked like a stone wall—and not at all far from the location given by the coordinates! Well, I just had to check it out, so I fought my way through and, once out on the foundation, saw the disk immediately. It's in very good condition, and coordinates and altitude were good.
Recovered in good condition as described. Handheld GPS coordinates for the bench mark are 41 46 43.3(N) 076 47 19.5(W).
