I recovered this California Department of Transportation survey disk from 1991 in good condition. It is an aluminum disk monumented on top of a low-lying boulder and north of a paved road leading west to the Lava Beds National Monument. A nearby orange carsonite witness post aids in recovery. The NGS coordinates and datasheet description are adequate for station recovery.
