Ice falls in a glacier are like water falls in a river. They form in steep sections of the glacier.
At these falls, flow is extremely fast, and the ice stretches and thins, often breaking apart to form blocks called seracs. Ice cover may not be continuous in these areas—there even may be sections where bare bedrock is exposed.
