Ah, a possible oasis in the rabid development of the Pigeon Forge commercialism. Checked out this BM while wife was shopping the complex to the east. Dr. Ogle's house now appears to be the Five Oaks Steakhouse. Checked east of the large oak tree (towards tehe Five Oaks Development office), but 16' away may now be paved. Will try again sometime as time allows.

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.
