Placing the telescopes in valleys is believed by some people to slightly reduce radio interference, but when radio telescopes are placed in valleys, it is usually because they are so large and the mountains work as supports, to reduce the cost.
U-shaped valleys are primarily formed by glacial erosion. As a glacier moves downhill, it erodes the sides and bottom of the valley through a combination of abrasion and plucking. Over time, the glacier carves out a wide and deep U-shaped valley, often leaving behind steep cliffs and a flat valley floor.
