LU0242 - USGS '309 B' Pipe Cap - Red Bluff, CA - U.S. Benchmarks on Waymarking.com

I recovered this U.S. Geological Survey pipe cap from 1902 (my oldest benchmark find to-date) in good condition. The pipe cap's surface has been marred somewhat and the stamping is hard to read but is still legible. This cap is listed on a topography map as 'BM 310' and also has the elevation stamping of '309.747' as well as the designation stamping of '309 B' on the cap face. This pipe cap is also slightly tilted in the ground and could affect surveying methods. My posted coordinates will place you very close to this cap. The NGS datasheet info is adequate for station recovery.
