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.

Famous quotes containing the word valley:
“All the Valley quivered one extended motion, wind
undulating on mossy hills”
—Allen Ginsberg (b. 1926)
“Ah! I have penetrated to those meadows on the morning of many a first spring day, jumping from hummock to hummock, from willow root to willow root, when the wild river valley and the woods were bathed in so pure and bright a light as would have waked the dead, if they had been slumbering in their graves, as some suppose. There needs no stronger proof of immortality. All things must live in such a light. O Death, where was thy sting? O Grave, where was thy victory, then?”
—Henry David Thoreau (1817–1862)
“I see before me now a traveling army halting,
Below a fertile valley spread, with barns and the orchards of summer,
Behind, the terraced sides of a mountain, abrupt, in places rising high,”
—Walt Whitman (1819–1892)
