IN MCHENRY, 11.4 MILES WEST ALONG THE BANTRY ROAD FROM THE CROSSING OF THE GREAT NORTHERN RAILWAY AT BARTON, PIERCE COUNTY, AT A CURVE TO THE NORTHWEST, 36 FEET WEST OF A ROAD JUNCTION, 24 FEET SOUTHWEST OF THE CENTERLINE OF THE NORTHWEST-AND SOUTHEAST ROAD, AT A JOG IN THE RIGHT-OF-WAY FENCE, 2.5 FEET NORTHEAST OF A FENCE CORNER, AND LEVEL WITH THE ROAD.

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.
