Radiating Valleys in Glaciated Lands

Abstract

Among the glacially-eroded landforms widely displayed in Scotland three have impressed me in the field as being particularly significant. First are the features known to continental workers as cirques or karen but in Britain by the Scottish word corrie. Second are the glacial troughs, especially those in which true rock basins have been developed. The third group comprise those areas, mostly lowland or low plateau but in some cases including the flanks and even the summits of mountains, in which the preglacial character of the surface has been so transformed that we may speak of the present forms as being ice-moulded. Fields of roches moutonnées obviously fall in this category.
