I recovered this U.S. & Geodetic Survey benchmark from 1954 in good condition, including the original wooden witness post. This disk is also listed on a topography map as 'BM 4714'. The NGS datasheet description is adequate for station recovery although Hackamore and Scarface no longer exist (former railroad siding stations) and Happy Camp Guard Station is now a fire station. This benchmark now resides below the highway due to road regrading and elevation. My more accurate coordinates will place you very close to this mark.
