found it while caching thank you

We found this Benchmark while geocaching nearby. It is not as easy to read as it was in the previous photo, but we are glad to see it is still here.

Found this one today while geocaching in the area.

Found this one with Dockdog easily in the wall. We also recovered the Triangulation mark & RM1. Found the Azimuth mark, east down the canal a couple of days later.
This is a standard NGS Reference Mark disk.

found with ikolor while in the area. needed this for a puzzle.

found it with radioman so we could get coords for a nearby puzzle.

Just going through the benchmarks I have seen before and catching up on logs.

Found! Inconceivable!

think it is a giving why we looked for this benchmark.

Son of bench this was hard to find!

Found under same reason as most.

Found it for a cache :)

I found this one while looking for GCM9A8... Just don't look down..

This one was a litlle tricky. Don't fall in the canal.

Passed this canal hundreds of times -- finally stopped and looked at it
Someone has ringed the mark with florescent red paint.

Found this one while out looking for "Micro Cache in a Tiny Park (Series 1 - No. 2) - GCM9A8". Pretty neat. Watch for big black snakes! Two of them almost got us as we were clearing the overgrowth looking for this benchmark.

I found this one while logging GCM9A8.

Like everyone else, found it while working on GCM9A8.

This was a quick and easy find early in the morning, nearly a park n grab! My first benchmark, and only done as part of the requirement for GCM9A8, which has been sitting on my 'nearest to home' list unfound for waaay too long. Finally, I can cross that one off my list!!

Don't fall in

Like others, went to find these for info to find a cache. Good thing I had read the info on its location, as my GPSr was pointing me off.

Well we finally did it!!! This is r FTF benchmark. Funny thing about it was that we swerved around a real snake in the road!!!

Found it with a little help from FLJ. Our GPS was being fussy and kept leading us to a 2nd benchmark located very close to this one.....

Found it as part of lororf series.

Found it right where it was supposed to be.

Last finder is on the money, watch your step or bring a towel...

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 March 1997.
  • 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.
