MW0234 - USC&GS 'N 602' BM - Modoc County, CA - U.S. Benchmarks on Waymarking.com

I recovered this U.S. Coast & Geodetic Survey benchmark from 1940 in good condition. The disk is monumented on top of a square concrete post projecting about 12 inches above the ground. There is a metal witness post near this station to aid in recovery. This BM is also listed on a topography map as 'BM 4179'. The NGS datasheet description is somewhat obsolete. The water tank in Perez is gone as well as the concrete culvert. My more accurate coordinates should place you very close to this mark.
