Cirques with small glaciers. Grossglockner, Austria.

Cirques, horns, aretes and cols. Their progressive development. In the first diagram, valley glaciers have produced cirques but, since erosion had been moderate, much of the original mountain surface has been unaffected by the ice. The result of more extensive glacial erosion is shown in the second diagram. In the final drawing, glacial erosion ha affected the entire mass and has produced not only ciques but also a matterhorn, and jagged knife-edged aretes. Leet and Judson, 1958, p. 235.
