|RECOVERY NOTE BY US GEOLOGICAL SURVEY 1982
3.4 MILE SOUTHEAST ON OLD US HWY. 95 FROM THE CAMAS PRAIRIE RR CROSSING, 0.4 MI W. OF THE P.O. AT CULDESAC, NEZ PERCE CO., ON THE WINCHESTER GRADE, 550 FT. NORTH OF A HOUSE, 110 FT. SOUTH OF A CORRUGATED IRON CULVERT WITH A CONCRETE HEADWALL AT THE WEST END, 32 FT. EAST OF THE CENTERLINE OF THE ROAD AND 1 FT. LOWER.

- 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.
