Abstract

This paper deals with the landforms and deposits produced by the glaciation of an area within the Southern Uplands. Two distinct phases of ice cover are described, and the landforms produced by the advance and retreat of the ice during each phase are discussed. Peeblesshire was covered by an ice sheet which attained a minimum altitude of 1750 feet and the centre of which was outside the area studied. The wastage of this ice sheet resulted in extensive erosion and deposition by meltwaters. A local valley glaciation, limited to the high ground in the south of the area studied, ploughed up the basal till deposited by the ice sheet. Well-developed moraines in five valleys indicate that this valley glaciation was limited in extent and descended to 1100 feet. It is suggested that the valley glaciation can be correlated with the Loch Lomond Readvance.
