Since this benchmark is part of the puzzle for finding "Ascension Gardens" (GCQ5QK), of course you'll find the benchmark too!

We were looking for the Ascension Garden cache and it said to note the benchmark number and log it seperately. We didn't know what it was talking about, but we listened anyway. When we got home I started logging in caches and I decided to look for this thing. Hey, it may be something new for us to find!

Found awhile ago while doing the cache nearby. Forgot to log it until now after finding another benchmark near another one.

ZFound this one as part of a clue to the Ascension Gardens cache which we promptly claimed a No Find for. Glad to have at least walked away claiming found something.

Working on a cache today which lead me right to this benchmark. I had forgotten just how many of these were around here!

Thanks for pointing us to it!!

This was in a somewhat unlikely place considering where these have been typically located on the few we've found.

Found this one easily while hunting down clues for the nearby "Ascension Gardens" cache. I've never seen a benchmark mounted in this orientation before...

Found it while surveying location for possible new cache. Pretty easy to spot, exactly where described.

We decided to look at benchmarks and found that this one was at the end of our street. Our son, Will, went with us and quickly found it.

Greetings Geocachers/Benchmarkers,

I found this just a little help from Bellclan. Now that I’ve studied it a bit, the description is indeed adequate for recovery. The coordinates seemed a bit off, but will certainly get you in the ballpark. Check out the small and almost hidden building next to the flower shop across from the Burger Kind in Lexington Park. Watch out for the vegetation. It’s there, exactly as described, a nice vertical mount.

Happy Benchmarking,
Ghosthunter

This was our first benchmark and proved harder that we originally thought. The directions were right on. (Do, Ry, Ri, Bi)

RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1991 0.9 KM (0.6 MI) SOUTHWESTERLY ALONG STATE HIGHWAY 146 FROM THE JUNCTION OF STATE HIGHWAY 235 IN LEXINGTON PARK, SET VERTICALLY IN THE SOUTH FACE OF THE ESSIX DRIVE WASTEWATER PUMP STATION NUMBER 4 BUILDING, 57.9 M (190.0 FT) SOUTHWEST OF THE CENTERLINE OF THE DRIVE, 23.0 M (75.5 FT) NORTHWEST OF THE HIGHWAY CENTERLINE, 0.6 M (2.0 FT) ABOVE THE GROUND SURFACE, AND 0.3 M (1.0 FT) WEST OF THE SOUTHEAST CORNER OF THE BUILDING.

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.
