I had taken the day off to resolve some personal issues, but as luck would have it, everything was cleared up on Friday. Instead of cancelling the day, I decided to go play in my new truck. I had been eyeing the Lonestar Day Challenge & one of the requirements is a benchmark. This is the closest one to my house that I haven't found. I've not done much benchmarking so I wasn't sure if I would succeed, esp since this one had not been found in 7yrs! I wandered around a bit, but enventually, I figured it out, lol!

Center of the top of the north headwall.

This benchmark is not as easy as some, but the description in the data sheet is good. You'll find it across the street from 6895 East Lancaster in southeast Fort Worth. Look for a culvert headwall on the north side of the railroad tracks. Use caution - trains come by here at relatively high speeds.

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.
