MW0623 - SPRR 'D 12 SPCO' Bolt - Siskiyou County, CA - U.S. Benchmarks on Waymarking.com

I recovered this Southern Pacific Railroad bolt in good condition. I've recovered other railroad bolts along railroad track and am sure they were monumented in 1919-1920. This bolt is monumented on top of a concrete abutment in the NW corner of a cattle crossing bridge and along railroad tracks. This bolt appears on a topography map as 'BM 4266'. The NGS coordinates are off but my more accurate posted coordinates should place you very close to this mark.
