Bergschrund on Mont Dolent

The bergschrund is the gap between the flowing ice of a glacier and the non-flowing ice that is frozen to the rock. Above the bergschrund, the mass of the ice and firn is not yet sufficient for it to start flowing under its own weight. Such a bergschrund can form beneath ridges and walls protruding from a glacier.

In contrast to "normal" crevasses , the bergschrund does not arise in the middle of the flowing ice, but on the edge. The bergschrund is not to be confused with the edge rift , which is a direct dividing line (as a melted chasm) between a glacier or a firn field and the rock.

In winter, the bergschrund is often filled with avalanche snow from the mountain flank above. With increasing depletion in summer, however, the bergschrund is often difficult to negotiate.
