Snow, Glaciers and Avalanches

As full glaciers develop, cirques become enlarged by plucking. (Gordon, 1977, Thorn 1979, Thorn and Hall 1980, Sharp 1988, Benn and Evans 1998, Hooke 1998). The distribution, orientation, and elevation of cirques can reveal a great deal about their development (Derbyshire and Evans 1976, Graf 1976). ................
