HR0597 "PP701 1943"

Spent the day in Madera County exploring some of the back-roads in and around the community of Raymond, California.  Found a few benchmarks while I was at it.

Located in rural Madera County, California, STATE, this USC&GS mark lies on the outside of a 90 degree corner, south and west of Road 613. The USC&GS mark stamped "PP701 1943" was found at 09:10, 16 November 2019 as described and in generally good condition. Go to description is adequate to find the mark.

Published NAD83 coordinates are located about 232 feet southeasterly of the found WGS84 coordinates. WGS84 coordinates for the mark found by 4 minute occupation with 7 strong satellites and 1 WAAS satellite.
