Found this benchmark while walking the Capital grounds.

Found near the capital building while visiting Austin and picking up virtuals on a business trip.

Saw the concrete block while touring the grounds after the capitol tour and figured it had to be a benchmark - and there was the disk. Also logged the nearby NORTH MERIDIAN benchmark bolt and two nearby virtual caches.

Actually stumbled across this benchmark by accident. I was on my way to the Archives building and looked at these two strange concrete pedestals wondering what they were. Found this benchmark disk on one of them and a strange bolt in the other. Found out when I got back home that they were both benchmarks. Wow! This mark was located in good condition at the place described.

We were doing some virtual caches around the Capitol when I stumbled across this.

So easy when your looking for the bolt!

Found this (my first Benchmark!) by accident while out geocaching with a group of 10 women! Very interesting ... just a few weeks ago I hadn't even heard of a benchmark and now I guess I'll be looking everywhere for them!

stumbled across this one during the ladies night out virtual cache tour of downtown

Found this one this morning while picking up some virtuals downtown. It just jumped right out at me - before now, I would have just walked right by! Thanks! Looks to be in great shape.

Found this one easily enough once we looked up and decided to look at the big unmarked monuments next to the capitol. Great to have Bud and Geno along for the fun. The pictures show that the benchmark is in great shape.

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.
