Abstract
A steady-state maximum ice sheet model is used to calculate basalt ice sheet temperatures for the bed of a former Scottish ice sheet similar in dimensions to that of the late Weichselian in this area. This model predicts the development of zones of basal melting and ice streams along topographic depressions such as large valleys and cold based ice over adjacent interfluves. Geomorphological mapping from aerial photography and field survey shows that these contrasts in basalt thermal regime coincide with evidence of glacial erosion and glacial protection respectively. The conclusion is that the overall pattern of ice sheet erosion can be explained by the pattern of modelled basal ice temperatures at the ice sheet maximum if convergence and divergence are included in the calculations. -Author
