|RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1990
2.2 KM (1.4 MI) SOUTHWESTERLY ALONG STATE HIGHWAY 23 FROM THE JUNCTION OF U.S. HIGHWAY 52 IN WAITE PARK, NEAR THE NORTHEAST END OF A 30 BY 35 FOOT AREA OF OUTCROPPING BEDROCK, 15.2 M (49.9 FT) SOUTHEAST OF THE NEAR RAIL OF THE BURLINGTON NORTHERN RAILROAD, 14.2 M (46.6 FT) NORTHWEST OF THE HIGHWAY CENTERLINE, 7.6 M (24.9 FT) SOUTHWEST OF UTILITY POLE NUMBER 693, 2.6 M (8.5 FT) SOUTHWEST OF THE NORTHEAST END OF THE OUTCROP, AND 0.6 M (2.0 FT) ABOVE THE LEVEL OF THE HIGHWAY.
- 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.
