In town on an airline layover and staying a few blocks away. Got out on a beautiful afternoon to walk around and grab a few local caches along the way. This is a very beautiful campus! Found the benchmark.
I'll upload a photo when I get home.

Saw this benchmark while caching in the area.

In the area for another, beautiful view

Found while in the area geo caching. in good shape.

I thought the nearby virtual cache might also be a benchmark, so I looked for nearby benchmarks. The virtual cache wasn't, but this was about ten feet away. There was a shirtless dude sunbathing about one foot away from this benchmark, so I had to explain myself. He seemed cool with it, though. Potentially awkward moment averted.

Found it close to the sundial.

Found it on our way back home to the Dallas TX area, going from Rhinelander WI (via the WI highpoint) to Rockford IL today. Mama Blaster found this disk while Daddy Blaster was working on a nearby cache.

Found this one while on campus for graduation. (Congrats "D" on your graduation!) After the ceremony we opted to find some geocaches. There is a virtual nearby.

Observation Point Cache or not?

WE found the nearby virtual cache, and I knew there was a benchmark very close from reading description of benchmark earlier.

were here doing near by cache, and figured why not log benchmark too.

This is a view from the benchmark location and the Observation Point cache of another virtual cache (Picnic Point) Really spectacular view!

Noticed this while looking for the Observation Point virtual cache. At the time we didn't know people kept track of these. Just thought it was interesting, so took a picture.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in November 1991.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • 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.
