What is the difference between bergschrund and Randkluft?
Table of Contents
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.

Why do crevasse and bergschrund create obstacles during mountaineering?
