Abstract
Periglacial landforms and deposits of Devensian age are commonly observed on the higher hill slopes of North Derbyshire but to date very few glacial features or sediments have been recognised. At Seal Edge, the escarpment slope has been sculptured by both frost and nivational processes but at Middle Seal Clough there are lobate ridges located beyond the talus foot that are probably moraines, formed during the Dimlington Stadial of the Late Devensian, by a small corrie glacier. The history of the ‘coombe’ has been interpreted from a study of both the inorganic and organic sediments and although the results are not conclusive, they indicate that ice and snow were important in the development of the coombe and that the peat formations in the basin also provide the earliest record to date for events in the vegetation history of the southern Pennine moorlands.
