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:
“To be seventy years old is like climbing the Alps. You reach a snow-crowned summit, and see behind you the deep valley stretching miles and miles away, and before you other summits higher and whiter, which you may have strength to climb, or may not. Then you sit down and meditate and wonder which it will be.”
—Henry Wadsworth Longfellow (1807–1882)
“How old the world is! I walk between two eternities.... What is my fleeting existence in comparison with that decaying rock, that valley digging its channel ever deeper, that forest that is tottering and those great masses above my head about to fall? I see the marble of tombs crumbling into dust; and yet I don’t want to die!”
—Denis Diderot (1713–1784)
““Over the mountains
Of the moon,
Down the valley of the shadow,
Ride, boldly ride,”
The shade replied,—
“If you seek for Eldorado!””
—Edgar Allan Poe (1809–1849)
