Glaciers

The bergschrund (Lliboutry et al., 1976) is the crevasse separating the glacier ice from
the rock in the upper part of the glacier head. Some ice adheres to the rock wall and the
rest of the glacier pulls away to form bergschrunds. They are located near very steep walls
(Fig. 2.29) and sometimes extend hundreds of metres. Frequently, instead of a single
crevasse, a system of bergschrund crevasses is developed.
