Abstract

The AA. present a case study from the high Drakensberg, comparing the contemporary spatial pattern of longest-lasting cold-season snow patches with the distribution patterns of active and relic cold region landforms. Two 30 m resolution sets of TM images (3 and 19 August 1990) and a DEM were used to demonstrate the geographic trends of snow patch depletion during late winter. Geomorphological phenomena with known coordinates were then incorporated into the GIS. The results lead to evaluating the relative importance of snow as an environmental control influencing landform distribution and formation within different topographic settings in the Drakensberg
