MW0818 - USC&GS 'BLUE' Triangulation Station - Modoc County, CA - U.S. Benchmarks on Waymarking.com

I recovered this U.S. Coast & Geodetic Survey triangulation station from 1931 in good condition. it is monumented on a large boulder and easy to spot from a small trail next to the boulder. the NGS datasheet log from 1948 is adequate for station recovery.
