Controls on sedimentation in a Late Devensian ice-dammed lake, Achnasheen, Scotland / Douglas I. Benn.

Title: Controls on sedimentation in a Late Devensian ice-dammed lake, Achnasheen, Scotland / Douglas I. Benn.
Author(s): Benn, Douglas I.
Date: 1989.
In: Boreas. (1989.), Vol. 18(1) (1989)
Abstract: Two distinct glacigenic sediment-landform associations are described. Firstly, three cross-valley ridges were associated with damming lobe of ice which directly controlled lake level. Secondly, large coalescing meltwater-fed deltas were developed in front of two outlet glaciers which initially terminated in western end of lake. Divergent evolution of two associations is explained with reference to differing relationships between ice thickness and lake level, flux of meltwater, and glacier activity.
