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 at the NW side of Spear Glacier approximately 40 km ESE of Witte Nunataks and approximately 24 km NNE of Mt. Leek, intersected station.

Survey mark - Highest Point.

Surveyed on 22 December 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.
