2nd benchmark for us!

Found it on a cold, blustery day. It was even framed by railroad spikes; easy, fun find.

Found It. The Southern Pacific Depot that is referenced has been relocated to a park off of 2nd and Main Streets and is now used as the Springfield Chamber of Commerce.

Quick find.

Found this quickly. It is clearly marked once you are within a few feet of it. SRG and I were out benchmark hunting today!

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. WARNING-Repeat measurements at this control monument indicate possible vertical movement.
  • 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.
