TattooBarbie was having an event down the street at billie jeans after the kyle geotour, since it was close by, i was able to walk off the burger and get a BM in the process.. All is as stated and doing fine...

Found it. It's still in good condition.

What an amazing find. This benchmark was working today. It was open with a big tripod over it, with something like a satellite device at the top. No one was around, but I got some good pictures.

Woohoo, my first TX benchmark find while in town for business. Found easily thanks to the description and Team GeoDillo's coordinates. In good condition, as described.

Coords were off, but the description helped us to zero in on it.

This benchmark was hidden under the tall grass but the survey tape on the utility pole helped us home in on it.

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.
