HR0602 "UU701 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, this USGS mark lies on the westerly corner of the T-intersection where Road 606 meets Road 415. The USGS mark stamped "UU701 1943" was found at 14:35, 16 November 2019 as described and in what looked to be good condition. There is a telecommunications riser and ground-mount service box within a few feet of the mark and witness post. I can't imagine that the utility services were placed there without compromising the integrity of the mark. Go to description is adequate to find the mark.
Published NAD83 coordinates are located about 262 feet southeasterly of the found WGS84 coordinates. WGS84 coordinates for the mark found by 4 minute occupation with 9 strong satellites and 1 WAAS satellite.

Control Text
- The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
- The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
- The geoid height was determined by GEOID99.
