GT1280 "J670 1942" - Revisited
Located in the City of Kingsburg, Fresno County, California, this USC&GS mark lies near the restored Kingsburg Railroad Station. The USGS mark stamped "J670 1942" was found at 11:30, 15 September 2018 as described and in generally good condition. Go to description is adequate to find the mark.
As stated in the title, this was a revisit. I originally visited this mark on 22 December 2002.
Published NAD83 coordinates are located about 476 feet southeasterly of the found WGS84 coordinates. WGS84 coordinates for the mark found by geo-positioning with a cell phone, but they correspond with the 475 foot error obtained with a handheld GPSr in 2002.
