How does a hanging valley form?

Answer 1

A tributary valley that joins a main valley where the latter has been deepened, usually by glacial erosion, resulting in a steep drop from the floor of the tributary valley to the floor of the main valley.

Answer 2

Similar to rivers, glaciers have tributaries. However as the main glacier erodes deeper into the valley, the tributary is left higher up the steep sides of the glacier. These U-shaped valleys ending with a water fall at the cliff-face are called hanging valleys.

When a river erodes the landscape, ridges of land form in its upper course which jut into the river. These are called interlocking spurs. A glacier removes these ridges leaving behind truncated spurs.

Answer 4

A hanging valley is the result of a glacier gouging a valley into the path of a larger glacier, much as tributary to a river would. The larger glacier carves out a deeper valley than the smaller tributary glacier and so the smaller valley is not as deep as the main valley and is said to hang.
