I recovered this U.S. Coast & Geodetic Survey azimuth mark from 1947 in good condition, although the concrete post this disk is monumented in has eroded severely on all four corners. There is no witness post to make recovery of this disk easier. Both reference marks and the triangulation station to this RYE series were recovered in good condition as well. The NGS datasheet info is acceptable for station recovery with the exception of the Pioneer Club that no longer exists. My posted coordinates should place you very close to this AZ Mark.
