MW0488 - USC&GS 'G 501' BM - Siskiyou County, CA - U.S. Benchmarks on Waymarking.com

I recovered this U.S. Coast & Geodetic Survey BM from 1954 in good condition. It is embedded in a low-lying lava rock boulder as part of a rocky outcrop. The NGS datasheet is now obsolete since virtually every reference landmark mentioned is either gone or has been rerouted. The lumber railroad is gone. Roads have been rerouted. This station appears on a topography map as 'BM 4830'. The NGS coordinates are way off but my more accurate posted coordinates should place you very close to this mark.
