The last glacier in Dovedale, Lake District.

Field mapping of moraine ridges and mounds in Dovedale, Lake District, has enabled the reconstruction of a small valley glacier. At its maximum extent the glacier covered an area of 3.39 km 2 and had an equilibrium line altitude of ~522 m. The presence of moraines in both the lower and upper parts of the valley suggests that the glacier underwent active retreat. Some of the ‘moraine ridges’ may have resulted from or been enhanced by fluvial erosion of thick drift sheets. Although the age of the moraines has not been determined it is inferred that the glacier developed during the Loch Lomond Stadial (12.9-11.7 ka BP). If this inference is correct the Dovedale glacier was the largest glacier to have developed in the eastern Lake District during this interval, and it probably connected across parts of the drainage divide with glaciers in neighbouring valleys.
