The U.S. Geological Survey marker at right is on our property, just north of our driveway, about halfway between the canal and the highway. It appears on USGS topological maps, but not in the Geodetic Survey's online database. I'm not sure why that's the case. The marker is still in great shape, with the following inscriptions:
U.S. GEOLOGICAL SURVEY BENCH MARK
FOR INFORMATION WRITE DIRECTOR WASHINGTON D.C.
COOPERATION WITH THE STATE
ELEVATION ABOVE SEA LEVEL 4840 FEET
31 WF 1954
This is the sort of marker used by the Geological Survey to make an altitude benchmark – a reference for local surveyors.
