I have seen this one plenty of times while in class to earn my A.A.S in land surveying

Logging this one as found today, although I have not only found it, but occupied it on numerous occasions. This is on the campus where I earned my Surveying degree, and I have had a level rod, a total station, and an Ashtech single frequency GPS receiver on it, all several times each. It is in great condition, other than the few punch marks in it that I can only assume are from other surveying students with poor aim.

Found as described and in good condition. As expected for a HARN disc, the coordinates are right on.

On a benchmark, county, and state park cache run with Secondgunman. This was the first on our list and we made the find with no trouble. The cords were good and we went right to it.

My first HARN benchmark, recovered in good condition on the UACCM campus. I'm guessing the PJTC indicates the benchmark was bluebooked when the campus was Petit Jean Technical College. Easy access with parking nearby. Normally I'd post coordinates, but my GPSr indicated 1 foot at the marker, which is not surprising for a HARN benchmark. Pretty neat.

Found with EBE. Very interesting.

Found as previously described, Coordinates are spot on. There is a stake marking the area and the marker was under a little bit of mud but visible.

Found this one while geocaching

Coords are right on the money (as with all HARN disks).

i also found this one while doing a level loop in Plane Surveying, i guess we kind of had to though for a grade

Found this one today while while doing a level loop.

Found disc in good shape around 5:45 pm. Found it without even turning on gps. Got out of car & found in less than one minute. Turned on gps to compare coordinates and they were an exact match! See gps in photo.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in September 1997.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • The geoid height was determined by GEOID99.
