KS1894 - USCGS 'CHICO RESET' Triangulation Station - Chico, CA - U.S. Benchmarks on Waymarking.com

I recovered this U.S. Coast & Geodetic Survey triangulation station from 1939-1961 in good condition. It is monumented fliush with the surface within Camellia Way Picnic Area (park) and near SW corner of Vallombrosa Ave and Pine Street intersection. Reference Marks 3 and 4 have been destroyed due to street widening. No attempt was made to recover Azimuth Mark. Reference Mark 5 was established in 1978 but doesn't appear in the NGS database and is monumented on top of a sidewalk curb, flush with the surface and about 20 feet north of the station. The NGS datasheet description is adequate for station recovery.
