GU3418 "MOWRY 1962" (Revisited)

Located in rural Fresno County, California, between the City of Kerman and the town of Mendota, this USG&GS mark lies on the south side of State Route 180 adjacent to a Ecological Reserve managed by the Department of Fish and Game. Found USG&GS mark stamped "MOWRY 1962" at 12:35, 07 April 2019 as described and in fair condition. While still in place, it looks as if it may have been hit by a car or possibly Caltrans equipment maintaining the shoulder of the highway. The accessory marks were not revisited at this time. Go to description is adequate to find the mark.

As stated in the title, this was a revisit. I originally visited this mark on 19 June 2004 and again on 22 November 2008.

Published NAD83 coordinates are located about 5 feet east of the found WGS84 coordinates. WGS84 coordinates for the mark found by 5 minute occupation with 12 strong satellites and 1 WAAS satellite.

Control Text

• The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in March 1994. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.

• The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)

• The Laplace correction was computed from DEFLEC99 derived deflections.

• The geoid height was determined by GEOID99.
