In geology, a valley or dale is a depression with predominant extent in one direction. A very deep river valley may be called a canyon or gorge.
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.

Below a fertile valley spread, with barns and the orchards of summer,
Behind, the terraced sides of a mountain, abrupt, in places rising high,”

undulating on mossy hills”

As that vale in whose bosom the bright waters meet;”
