U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins. Varves are a very useful yearly deposit that forms in glacial lakes.
Q. How do you tell if a valley was formed by a glacier?
They have a characteristic U shape in cross-section, with steep, straight sides and a flat or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in cross-section). Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring.

A former tributary glacier valley that is incised into the upper part of a U-shaped glacier valley, higher than the floor of the main valley. Hanging valley streams often enter the main valley as waterfalls. A hanging glacier connects the upper valley to the lower valley. …
Q. Why are they called hanging valleys?
They can also be called as tributary valleys to larger valleys. These valleys are known as hanging valleys primarily because of their unique position. Besides, the valleys that are above the main valleys are always known as hanging valleys. Hanging Valleys can always be spotted in the form of a U-shape.
Q. Where is a hanging valley?
Hanging valleys are found in mountainous regions, and Montana’s Glacier National Park has one major hanging valley; the Birdman Woman Falls. California’s Yosemite National Park is home to numerous hanging valleys.
Q. Is Yosemite Falls a hanging valley?
Famous Hanging Valleys These include Yosemite Falls, Ribbon Fall, Bridalveil Fall and Illilouette Fall. Glaciers cut and formed both valleys, a smaller glacier in the upper valley feeding the larger glacier down below. A glacier of larger size and depth creates more erosion and cuts deeper into the land.
