Figure 4. The subglacial valley system at Amundsenisen which was mapped in more detail, shown with a 2× vertical exaggeration andcontour interval of 25m. The bed surface has been corrected for the ice surface topography. Data on bed and ice sheet topography werecollected with a spacing of 500m or less along the profiles, shown by the dotted lines on the upper ice surface. The general valleymorphology indicates that the valley was formed by erosion by a wet-based local mountain glacier. This site is used for a comparative

calculation of basal temperature for discussing where, on a local scale, preservation of landforms may occur
