Saw this one when we renewed our license plates. It looked like several discoveries documented this benchmark with photos, so I did not take any.

Walked right by it on my way to Zesto! Yum Yum!

Found it today. Good condition. See attached pictures. Higher quality pictures available upon request.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
