Confirming this one is still around.

No wonder I couldn't find it before. I was looking at the wrong darn building. It is on the front of the building in front of the Upper Limits climbing gym. Now that I found the right building, the directions made good sense. Coordinates I got were N40.28.733 W089.00762.

The disk is on the wall behind the green air conditioner and the bush a couple feet off the ground.

I didn't find it but think this is now the Upper Limits climbing gym. I'm going to look again but the disk may have been covered up by some remodeling on the corner of the structure of the gym where the disk is. I looked a second time and still seems the disk must be covered by remodeling or hidden by a fence enclosing a private residence there. Someday, maybe I'll get enough nerve to go in and ask the people inside if they know about it.

Documented History (by the NGS)

01/01/1954 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1954 1.2 MI W FROM BLOOMINGTON. ABOUT 1.25 MILES WEST ALONG THE NEW YORK CENTRAL RAILROAD FROM THE FREIGHT STATION AT BLOOMINGTON, ABOUT 0.1 MILE WEST OF MILE POST IND 167, SET VERTICALLY IN THE NORTH FACE OF CONCRETE FOUNDATION OF MAIN OFFICE OF FUNK BROS. SEED COMPANY, 67 FEET SOUTH OF SOUTH RAIL OF MAIN TRACK, 2 FEET EAST OF NORTHWEST CORNER OF BUILDING, ABOUT 2 1/2 FEET ABOVE GROUND AND ABOUT LEVEL WITH TRACK.

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.
