Documented History (by the NGS)
|01/01/1954 by NPS (MONUMENTED)
|DESCRIBED BY NATIONAL PARK SERVICE 1954 (ELJ)
STATION IS LOCATED ABOUT 24 MILES NORTH OF NORTH WILKESBORO, 10 MILES NORTHEAST OF MULBERRY GAP AND 3 MILES SOUTH OF WHITEHEAD, ABOUT 125 YARDS NORTHWEST OF THE BLUE RIDGE PARKWAY, ABOUT 75 FEET WEST OF THE HIGHEST POINT OF A BARE HILL AND 3 FEET SOUTHEAST OF A FENCE LINE. THE MARK IS A 4 X 4 INCH CONCRETE POST PROJECTING ABOUT 8 INCHES WITH A 2 INCH USDI NPS ROUND BRONZE DISK IN THE TOP STAMPED 2-C 394 3-40.
A TRAVERSE CONNECTION WAS MADE FROM TRIANGULATION STATION BLUFF TO THE DOT IN THE CENTER OF USDI NPS DISK AND THE DISTANCE IS 98.42 FEET, 29.998 METERS.
TO REACH THE STATION FROM THE JUNCTION OF STATE HIGHWAY 18 AND BLUE RIDGE PARKWAY ABOUT 21 MILES NORTHWEST OF NORTH WILKESBORO, GO NORTHEAST ON BLUE RIDGE PARKWAY FOR 9.6 MILES TO A SIDE ROAD RIGHT TO OLD DWELLING, CONTINUE ON PARKWAY FOR 1.0 MILE (THIS IS 0.1 MILE BEFORE REACHING AIR BELLOWS GAP) AND END OF TRUCK TRAVEL. PACK NORTHWESTERLY UP HILL TO FENCE LINE AND STATION AS DESCRIBED.
- The North Carolina/South Carolina HARNS have been completed but, due to contractual restrictions, coordinates for these stations will NOT be published in the near future. In the interim, the published coordinates in North and South Carolina will not be consistent with the Continuously Operating Reference Stations (CORS). The HARN coordinates for these stations are available upon request. Contact Gary Thompson(919-733-3836), or Lewis Lapine(803-896-7700). In addition, the published North and South Carolina positions (NAD 83 (1986)) are NOT consistent with those determined in adjacent state readjustments. The discontinuity between stations located in North or South Carolina and those in adjacent states which have been adjusted to the HARN may be as much as 5 decimeters. This will result in a significant loss of accuracy over lines crossing such state borders.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in July 1986.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
