A field differential Geopositional Satellite (GPS) survey team which included Jim Garvin, Jack Bufton, Bill Krabill, and Earl B. Frederick deployed a pair of Motorola Eagle II GPS receivers to the southern flanks of the feature known as Mars Hill (an alluvial boulder field superimposed on a major lobe of alluvial and colluvial material in Eastern Death Valley) on Oct. 19, 1989. The objective was to measure the 5-20 cm scale microrelief of the boulder field at pixel scales (30-50 m long transects), with vertical control to the few cm level. These microterrain profiles were to be used to help calibrate radar scattering models, and to compare with helicopter stereo data (FEXP-E-HSTP-4 RDR-TOPOGRAPHIC-PROF-V1.0) for the same location.
