What Are U Shaped Valleys?
A U-shaped valley is a geomorphological formation that has steep, high sides and a rounded or flat valley bottom. These valleys are formed by glaciation. They usually contain lakes or rivers, sandtraps along a golf courses kettle lakes (water hazards) or other natural features.
Glacial erosion forms U-shaped valleys when the rocks are removed from the sides and the bottom of the valley. These valleys are common in mountainous regions all over the globe.
They are formed by glaciers
Glaciers are huge bodies of ice that are formed on mountains, and then move down them. When they degrade the landscape, they create U-shaped valleys that have flat floors and steep sides. These valleys differ from river valleys that are typically designed to look like the letter V. While glacial erosion may be seen in a variety of places, these valleys are especially characteristic of mountain areas. They are so distinct that you can discern whether the landscape was created by rivers or glaciers.
The formation of a U-shaped valley starts with an existing V-shaped river valley. As the glacier melts, it encroaches upon the V-shaped valley of the river, and forms an inverted U-shape. The ice also scratches the surface of land creating straight and high walls along the sides of the valley. This process is referred to as glaciation and requires a lot of strength to scour earth in this way.
As the glacier continues to degrade the landscape, it makes the valley larger and deeper. The glacier's ice is less abrasive than the rocks. As the glacier travels down the valley, it creates abrasion on the rock surfaces and pulls the weakend rocks away from the valley walls in a process referred to as plucking. These processes work together to broaden, deepen and smooth the U-shaped valley.
This can cause a small valley to 'hang above the main one. The valley could be filled with ribbon lakes that are formed when water rushes through the glacier. The valley is also characterized by striations, ruts and striations on the sides and the floor, as well as till and moraines on the floor.
The world is full of U-shaped valleys. They are most common in mountainous regions, including the Andes, Alps, Caucasus, Himalaya and Rocky Mountains. In the United States they are usually located in national parks. Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana. In certain instances the valleys can extend to coastal locations and then become Fjords. This is a natural process that occurs when the glacier melts. It can take thousands of years to create these valleys.
