I found this with Crowesfeat30 & Quailman2 during Geocoinfest. It is in good shape and an easy find right next to the road. Look out for the little stinging ants.

Found this today while in the area for the Geo Coin Fest. My target was to find as many different types of hides as possible including a benchmark. Asked the guy at the entrance booth if I could go past to look for this really fast without paying and he let me in, yeah. Found 12 different types of caches including this benchmark. What a great geocaching day.

About 80-100 feet NNE of this benchmark there is another that's not in GCs database, because their data was acquired in 2000 and never updated. There was a wooden post with pink ribbons beside it (see picture) that surely won't last long.

I'm posting coordinates and pictures of it here since there's no where else on GC.com. It's identification is

AJ6401 HGCSD 52 RESET

I was being pressured by a guard and there were no meaningful references, so I didn't take a wider view.

Here is the description:

[b]DESCRIBED BY HARRIS-GALV CO DIST 2000 (WMC): THE STATION IS LOCATED ABOUT 33.5 KM (20.80 MI) SOUTH EAST OF HOUSTON, 4.4 KM (2.75 MI) NORTH OF LEAGUE CITY.

This benchmark is inside the Space Center Houston theme park. The coordinates posted by the previous finder are good enough I didn't take any.

I parked in the small area near the entrance off of NASA 1, where the trainer jets and a mockup of the Apollo spacecraft are on display, and walked in -- staying outside until I reached the fence in the back and then walked along the green area next to the fence. It was about 8am on Sunday and the theme park hadn't opened but workers were showing up.

I must have been there about 15 minutes when they sent a guard to see what I was doing. By this time I was at the second benchmark (see note following this log). We exchanged remarks (that is, I stalled him off) while I took coordinates and pictures. When I was through, I explained I was leaving and he watched me leave.

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.
