... ( Harbor, 1992 ). This difference in glacial erosion rates broadens and steepens the valley and progressively deepens its floor, resulting in the formation of a typical U-shaped valley. The upper concave valley profiles were thus sculpted and enlarged by glacial erosion whereas the lower V-shaped profiles...
