This "easy roadside bench mark" was more of a challenge than we'd expected. It was in an awkward place to reach and to photograph, and we had plenty of thorny branches to clear before we could even get a good look at the mark. The mark is in good condition; however, a new bridge has been built and this old bridge deprecated. I wonder whether its days are numbered.

A report on the condition of this survey mark has been submitted to NGS, along with the following recovery note:

Handheld GPS coordinates for the station are 41 06 5.2(N) 074 57 44.6(W).
