|DESCRIBED BY COAST AND GEODETIC SURVEY 1960 (NES)
STATION IS LOCATED ON THE WEST RIGHT-OF-WAY OF U.S. HIGHWAY 75, ABOUT 3-1/2 MILES NORTH OF HOLTON.
REACHED FROM THE JUNCTION OF U.S. HIGHWAY 75 AND STATE HIGHWAY 16 IN THE WEST EDGE OF HOLTON BY GOING NORTH ON HIGHWAY 75 AND 16 FOR 3.05 MILES TO WHERE HIGHWAY 16 TURNS WEST, CONTINUE NORTH ON HIGHWAY 75 FOR 0.4 MILE TO THE STATION ON THE LEFT.
STATION MARKS ARE STANDARD DISKS, STAMPED SKIRT 1960. THE SURFACE MARK IS SET IN THE TOP OF A 10-INCH SQUARE, CONCRETE POST PROJECTING 6 INCHES. IT IS 68 FEET WEST OF THE CENTERLINE OF HIGHWAY 75 AND 3.8 FEET SOUTH OF A METAL WITNESS POST.
REFERENCE MARK 1 IS A STANDARD DISK, STAMPED SKIRT NO 1 1960, SET IN THE TOP OF A CONCRETE POST PROJECTING 6 INCHES. IT IS 65 FEET WEST OF THE CENTERLINE OF HIGHWAY 75 AND 79.6 FEET NORTH OF THE WITNESS POST.
REFERENCE MARK 2 IS A STANDARD DISK, STAMPED SKIRT NO 2 1960, SET IN THE TOP OF A 10-INCH, SQUARE, CONCRETE POST PROJECTING 6 INCHES. IT IS 71 FEET WEST OF THE CENTERLINE OF HIGHWAY 75 AND 88.3 FEET SOUTH OF THE WITNESS POST.

|RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1961
3.5 MI N FROM HOLTON. 3.5 MILES NORTH ALONG HIGHWAY 75 FROM THE JUNCTION OF U.S. HIGHWAY 75 AND STATE HIGHWAY 16 IN THE WEST EDGE OF HOLTON, 68 FEET WEST OF THE CENTER OF U.S. HIGHWAY 75, 4.0 FEET SOUTH OF THE WITNESS POST, SET IN THE TOP OF A 10 INCH SQUARE POST THAT PROJECTS 6 INCHES.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in October 1998.
- The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- 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.
