I recovered this U.S. Coast & Geodetic Survey benchmark from 1940 in good condition. It is monumented on top of the SE wingwall of a concrete culvert under railroad tracks. This BM also appears on a topography map as 'BM 4035.9 U 603'. The NGS datasheet is adequate for station recovery. My more accurate coordinates will place you very close to this mark.
