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 in the SW end of the Sweeney Mountains approximately 36 km ESE of Mt. Wasilewski, approximately 15 km N of Morgan Nunataks and approximately 9 km S of Mt. Ballard on the highest point on Mt. Smart, intersected station.

Survey mark - highest rock top.

Surveyed on 20 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.
