Found this around midnight. I'd seen it before. Everyone else's coordinates are right on so I won't bother posting mine. They're much better than USGS's.

Second of 3 easy benchmark finds during a day of biking and caching.

These coordinates should be better than the ones given. They didn't have sputniks in the sky when they made these.

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.
