A canyon
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, at least with respect of the cross section of the slopes or hillsides. A valley formed by flowing water, or river valley, is usually V-shaped. The exact shape will depend on the characteristics of the stream flowing through it. A valley carved by glaciers, or glacial valley, is normally U-shaped. The valley becomes visible upon the recession of the glacier that forms it.
