This is the first of four benchmarks that I found today. This old building is quite beautiful, it's hard to believe that it was a post office at one time. Then again, post offices seemed more important in the days gone past. The benchmark is in good shape, right where the description said it would be.

Recovered in Good condition. GPS coordinates are, N 36º 19.647 W 119º 38.758. Altitude 257 ft. Disk is stamped, U 157 1933. Digital photos available.

Found USC&GS benchmark stamped 'U157 - 1933' at 16:30, February 21, 2009 as described and in good condition. Go to description is adequate. The building is no longer used as a post office, but is a branch office for Rabobank.

Published NAD83 coordinates are located about 180 feet southerly of the found WGS84 coordinates. WGS84 coordinates for the mark found by 2 minute occupation approximately 15 east of the mark with 5 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  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.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.
