The Deglaciation of Eastern Eskdale, Yorkshire

Summary The ice-marginal features of eastern Eskdale include glacial drainage channels, ice-marginal benches, twin parallel streams, gorges, moraines, kame terraces and lobe edge embankments. Four types of glacial drainage channel have been recognized: strictly marginal, submarginal, compound and subglacial. The compound examples were initiated by subglacial streams and further developed by subaerial meltwaters. Throughout the area there are two recognizable retreat stages; during each a considerable proportion of the glacial drainage was ice-marginal but subsequently, as the ice became more fragmented, englacial, superglacial and subglacial streams became dominant.
