I recovered this U.S. Coast & Geodetic Survey station mark from 1968 in good condition. The nearby reference mark's disk was found missing but the stem was found projecting on top of the boulder. This disk series is also listed on a topography map as 'AVILA'. The NGS datasheet description and NGS posted coordinates are adequate for station recovery.
