I recovered this U.S. Coast & Geodetic Survey benchmark from 1954 in good condition. This disk is also listed on a topography map as 'BM 4140'. The NGS datasheet description is adequate for station recovery although the wooden bridge over the canal is gone and has been replaced by an elevated dirt road. This road next to this disk was the former County Road 93 and has been realigned to the south. This dirt road may now be on private property. The wooden witness post is gone. My more accurate coordinates will place you very close to this mark.
