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

Research output: Contribution to journal › Article › peer-review

Abstract

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 and suggests that the last ice sheet descended westwards across Knoydart from c. 1000 m to c. 900 at the west coast, implying that most theoretically-based ice-sheet models are substantially in error in this area.
