Right next to the sprinkler!

Found while caching and visiting the aquarium with my family on the way home.

Found this Benchmark (FC1183) as one of several on my first time hunting Benchmarks. Beautiful courthouse. Grounds were under construction so was not able to look for the other one nearby in the grass (FC1182).

Found it

It's still there.

Was in the area today with villagecachers and stopped by to find this mark.

Found as described, about 12 feet south of the flagpole and at handheld coordinates N35-02.919 W085-18.414.

Looking north at the south entrance to the county courthouse, the mark is at the white notebook, center.

Smiley for me

Right where it supposed to be!

Looks like it is there. Maybe the '83 crew just wasn't looking too closely. They probably had a long lunch at the Brass Register...

N 35° 02.915 W 085° 18.416

Funny how this is listed as missing. It's there in plain sight!

As described, but it doesn't come up in every search of the nearby caches.

Recovered as described. Stamped M41 1934. Found this one while doing a nearby cache.

N 35° 02.916 W 085° 18.412

17 August 2003, Recovered in good condition, as described by Coast and Geodetic Survey 1950.
We found and photographed this Benchmark today, along with FC1182 at the Courthouse east entrance. The Benchmark is securely located in a very obvious location, directly in front of the Courthouse flagpole, directly in the middle of the Courthouse south entrance walks as described. How did the NGS miss it in 1983, and then the Power Squadron found it in 1989 & 1998, as we did today?! It's there, check it out.

This is the view from across 7th Street, looking northward up the south entrance walks to the south entrance of the Hamilton County Courthouse. The Benchmark, and Chip's Map 330, are located directly in front of the flagpole at the top of the steps up from the 7th Street sidewalk.

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.
