Found a drill hole, but I can't be certain weather it was the station or one of the reference marks. A swarm of mosquitoes and years worth of moss kept me from searching too thoroughly today. I'll come back better prepared.

|DESCRIBED BY US LAKE SURVEY 1872
THIS STATION IS SITUATED ABOUT THREE-FOURTHS OF A MILE NORTHEAST FROM THE NORTHEAST SIDE OF LAKE WINNEBAGO, AND NEAR THE LINE BETWEEN HARRISON AND WOODVILLE TOWNSHIPS, CALUMET COUNTY, WISCONSIN. IT IS ABOUT 20 FEET BACK FROM THE EDGE OF THE LIMESTONE LEDGE RUNNING NEARLY PARALLEL WITH THE EAST SHORE OF LAKE WINNEBAGO. THE HEIGHT OF THE STATION USED WAS 35 FEET. THE GEODETIC POINT IS MARKED BY A HOLE DRILLED IN THE SOLID ROCK. ABOVE THIS IS PLACED A MARKING STONE OF THE ORDINARY FORM, SURROUNDED BY A PILE OF SMALL STONES. THREE REFERENCE MARKS WERE MADE. THE FIRST OF THESE IS A HOLE DRILLED IN THE ROCK BETWEEN THE LETTERS U.S. CUT THEREON. IT BEARS SOUTH 83 DEG 15 MIN WEST, AND IS 25.25 FEET DISTANT FROM THE GEODETIC POINT. THE SECOND REFERENCE MARK IS A CIRCLE AND AN ARROW CUT IN THE ROCK, THE ARROW POINTING TOWARD THE GEODETIC POINT. THE CENTER OF THE CIRCLE BEARS NORTH 32 DEG 14 MIN WEST, AND IS 11.93 FEET DISTANT. THE THIRD MARK IS A HOLE DRILLED IN THE ROCK. IT BEARS NORTH 44 DEG 52 MIN EAST, AND IS 46.97 FEET DISTANT FROM THE GEODETIC POINT. (PROFESSIONAL PAPERS NO. 24).

- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in November 1991.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
