Record #96856:

Avalanche impact landforms on Ben Nevis, Scotland / Colin K. Ballantyne.

Title: Avalanche impact landforms on Ben Nevis, Scotland / Colin K. Ballantyne.
Author(s): Ballantyne, Colin K.
Date: 1989.
In: Scottish Geographical Magazine. (1989.), Vol. 105(1) (1989)
Abstract: First identification in Britain. Consists of 75 m long boulder rampart, which crosses bedrock step and dams small tarn. Tarn is inferred to have been excavated by repeated avalanche impact and rampart to have formed by accumulation of debris thrown up by impacting snow avalanches. Aprons of loose debris extending downslope are considered to represent deposition in avalanche runout zones. Abundant recently-deposited boulders on rampart and debris aprons indicate recent accumulation and suggest that geomorphic effectiveness of avalanching snow in Scottish mountains may be more marked that hitherto thought.
