A Late Devensian nunatak on the Knoydart Peninsula, NW Scotland: implications for ice-sheet reconstruction

Geomorphological mapping and analysis of soil mineralogy indicates that all summits on the Knoydart Peninsula were over-ridden by the last ice sheet apart from Ladhar Bheinn (1020 m), where the ice attained a maximum altitude of c. 950 m. This figure is consistent with evidence from adjacent areas a...
