Got this one as I was heading back to the hotel for the evening. Coordinates are close for this benchmark.

While vacationing on M.D.I. I decided to search for a few local benchmarks. This one, like many of the others I had hunted, was found during a very pleasant after-breakfast walk around town. Locating this mark was relatively easy using the historical description. At the station my Garmin GPSmap76 receiver indicated only 9 feet from the posted coordinates. The disc is quite visible and is in excellent condition. ~Rich in NEPA~

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 January 2001. No vertical observational check was made to the station.
  • 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.
