I recovered this U.S. Coast & Geodetic Survey benchmark from 1935 in good condition. This disk is also listed on a topography map as 'BM 5483'. The NGS datasheet description is adequate for station recovery although the original wooden witness post is gone. My more accurate coordinates will place you very close to this mark.
