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 end of the Sweeney Mountains approximately 33 km NW of Mt. Smart and approximately 22 km ENE of Mt. Wasilewski on lone nunatak on the E and upper side of exposed rock approximately 1.5 meters lower than highest point of snow covered peak, monumented station.

Survey mark - Standard USGS tablet set in drill hole in rock outcrop, stamped "BECKI 1977-1978".

Surveyed on 15 January 1978.

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.
