Searched for California Division of Highways (CDOH) Triangulation Station stamped "PRATTON AZ MK" at 13:00, 31 March 2012. The benchmark was not located and believed to be destroyed. The northeast corner of the intersection has been widened and the approximate location for the mark is now covered in asphalt. The mark is described as being 7 feet west-northwest of a gas line marker. A small gas utility manhole is present in the pavement. The approximate location for the mark, measured from the centerlines of the roads, is about 7 feet west-northwest, from the small manhole. No new coordinates were taken.

There is a Department of the Interior Geological Survey mark set in a canal headwall structure near the location. It is NOT the azimuth mark.

GT2111 "PRATTON Azimuth mark" - The location for this mark now lies in the street, adjacent to the gas line manhole. The mark is most likely destroyed.
