Documented History (by the NGS)
| 1/1/1971 by NCGS (MONUMENTED) |
| DESCRIBED BY NORTH CAROLINA GEODETIC SURVEY 1971 (LWA)
LUMP IS A N. C. GEODETIC SURVEY TRAVERSE STATION ESTABLISHED IN THE VICINITY OF DEEP GAP, NORTH CAROLINA.
LUMP IS LOCATED APPROXIMATELY 8.0 MILES NORTHEAST OF DEEP GAP AND 15.0 MILES NORTHWEST OF N. WILKESBORO. TO REACH STATION PROCEED FROM THE INTERSECTION OF NC 16 AND THE BLUE RIDGE PARKWAY. GO SOUTH ALONG THE PARKWAY FOR 3.2 MILES TO THE LUMP OVERLOOK ON LEFT AND STATION APPROXIMATELY 600 FEET DUE SOUTH ON TOP OF THE LUMP.
STATION MARK IS A STANDARD N. C. BRASS TRAVERSE DISK, STAMPED LUMP 1971, SET IN THE TOP OF A CONCRETE CYLINDER, THE TOP OF WHICH IS FLUSH WITH THE GROUND.
MARK IS 520.0 FEET S OF ALUMINUM REF. TAG ON SPLIT RAIL FENCE POST AT VEHICLE DRIVE IN GATE. 520.0 FEET SSE OF ALUMINUM REF. TAG ON A SPLIT RAIL FENCE POST AT WALK IN GATE. |

| RECOVERY NOTE BY NORTH CAROLINA GEODETIC SURVEY 1981 (ESL)
THE STATION WAS RECOVERED AT THIS DATE. STATION IS IN GOOD CONDITION AS DESCRIBED, EXCEPT FOR THE FOLLOWING CORRECTION. THE STATION IS SET IN A ROCK OUTCROP NOT A CONCRETE CYLINDER.
MARK IS A NCGS STATION. |
Control Text
- 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Carolina HARNS have been completed but, due to contractual restrictions, coordinates for these stations will NOT be published in the near future.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 November 1993.
- The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
