It is formed by the melting of ice against warmer rock and may be very deep. During summer therefore, a randkluft will become wider and thus more difficult for climbers to negotiate. Randklufts are often found in relatively low-lying glaciers such as the
Blaueis in the
Berchtesgaden Alps or the
Höllentalferner in the
Wetterstein. A randkluft is similar to, but not identical with, a
bergschrund, which is the place on a high-altitude glacier where the moving ice stream breaks away from the static ice frozen to the rock creating a large crevasse. Unlike a randkluft, a bergschrund has two ice walls. == Gallery ==
