Abstract

Synopsis Palynological evidence for the age of ice-dammed lacustrine deposits at an infilled lake basin at the SW end of Loch Awe shows the lake and the kame deposits forming the dam to be of Loch Lomond Stadial age. The absence of Devensian Lateglacial sediments at six sites within the Awe valley, and the virtual synchroneity in the earliest Flandrian of their basal biostratigraphic records also indicates ice cover in the valley during the Loch Lomond Stadial. This evidence is at variance with recent reconstructions of the extent of this ice advance in this part of Scotland. Similar lines of evidence from other localities in adjacent valleys suggest that the Loch Lomond Readvance in this region was of markedly greater magnitude than currently envisaged.
