[1] 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).

A glacier can take anywhere from 10,000 to 100,000 years to flatten out the bottom of a V-shaped valley and create a U-shaped valley. Over long periods of time the sandpaper-like quality of the moving ice and rock scours and reshapes the land into broad U-shaped valleys, sharp peaks, and lake-filled basins. The interlocking spurs in the narrow V-shaped river valley are cut-off by the ice, creating truncated spurs. The hanging valleys are so named due to their positioning of being above main valleys. U-shaped valleys are unique as they have much broader bases with steep and straight walls compared to typical V-shaped valleys, which have narrow bottoms and steep walls having V-shape in the cross-section. The 1950s movie, The Inn of the Sixth Happiness, also filmed in this location. Half-way along this straight line, Cntaro Magro summit and the pyramid of Torre emerges from the jagged edge of the glacial cirque.

Glacier Landforms. By the same process, glaciers tend to narrow the bedrock divides between the upper reaches of neighbouring parallel valleys to jagged, knife-edge ridges known as artes. The first variation remains in the form of the Rocky Mountain model that is attributed to alpine glacial valleys with an overall deepening effect on the valley. When the ice thaws or recedes, the valley is often littered with small boulders carried within the ice, called glacial till or glacial erratic. The combined rock formations that occur in Waterton-Glacier are part of the Precambrian Belt Supergroup, and can be seen above treeline in one-third of the park. Look it up now! What is the difference between AV and U-shaped valley? Artes also form between two, valley is converted to a U-shaped valley because the U-shape provides the least frictional resistance to the moving glacier. A vale is a particularly wide river valley. U-shaped valley walls are straighter than V-shaped valleys due to the non-bending glaciers movement. These are the moraines. Side valleys are formed by tributaries to streams and rivers and feed the main stem. One of the famous U-shaped valleys is the Nant Ffrancon Valley in Snowdonia, Wales. After formed, these glaciers begin to move, sliding slowly down the side of the mountains and into the valley below.

A U-shaped valley is a valley that has a profile suggesting the form of the letter "U," characterized by steep sides that may curve inward at their bases and a broad, nearly flat floor. As the movement of the glaciers gets constrained by the V-shaped valley, the force is concentrated in the floor. Because a glacier has a much greater viscosity and cross section than a river, its course has fewer and broader bends, and thus, the valley becomes straighter and smoother.
