Abstract
Field mapping and evaluation of morphological and some sedimentological characteristics indicate that three debris accumulations in the hills centred on Knott in the northern Lake District result from glacial deposition. Another debris accumulation is interpreted as a pronival (protalus) rampart that developed at the downslope margin of a former snowbed. A Loch Lomond Stadial (LLS) age (11-10 k 14 C years bp ) is inferred for all the landforms and extends distribution of LLS glaciation into a new area of the Lake District. Reconstruction of the former glaciers reveals that two had larger surface areas than a substantial number of previously recognized LLS glaciers and estimated equilibrium line altitudes were lower than those for glaciers in the neighbouring Blencathra group hills. Glacier and snowbed development were favoured by site aspects, which provided protection from direct solar radiation, and occurrence of adjacent high ground, from which snow could be transferred by wind to contribute to glacier and snowbed mass. It is possible that other LLS glacier and snowbed sites in the Lake District remain to be discovered.
