MW0226 - USC&GS 'W 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, including the original wooden witness post. The concrete culvert mentioned in the datasheet description was destroyed after a road-widening project in the 1980s. This benchmark is also listed on a topography map as 'BM 4611'. The posted NGS coordinates are adequate for station recovery.
