1977-78 Season
Engineers: David Reed, Eberhand G. Schirmacher, Robin Schumtzler,
and Harry Zohn, Jr.
Intersected peak positions determined by terrestrial surveys
employing Wild T-2 theodolite for angular measurements and Electro-tapes
for distance measurements from positions developed by geoceiver (Doppler)
observations.
Elevations based on sea level using the NASA Goddard Earth
Model (GEM) 10B.
Located in Ellsworth Land an isolated nunatak approximately 40 km N
of Mt. Leek, approximately 34 km SE of Mt. Edwards, and approximately 16
km E of Witte Nunataks, intersected station.
Survey mark - Highest point.
Surveyed on 30 November 1977.
Horizontal Datum - The positions are based on WGS 66 datum. The adjusted
network was fitted to the geoceiver stations by a least squares transformation
and the residuals were less than two meters.
Vertical Datum - Geodetic heights corrected to the geoid using NASA
GEM 10B. No direct connections to sea level were made.l.
