The Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River.. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.

A canyon "flashes" when a large amount of precipitation falls in the drainage, and water levels in the canyon rise quickly as the runoff rushes down the canyon. In canyons that drain large areas, the rainfall could be many kilometers away from the canyoners, completely unbeknown to them.
This side canyon of Grand Coulee in Washington was carved by the Missoula floods. A view through a coulee in Alberta, with steep but lower sides, and water in the bottom. Coulee, or coulée (/ ˈ k uː l eɪ / or / ˈ k uː l iː /), [1] is any of various different landforms, all of which are kinds of valleys or drainage zones.
A beam of sunlight in Upper Antelope Canyon. A slot canyon is a long, narrow channel or drainageway with sheer rock walls that are typically eroded into either sandstone or other sedimentary rock. A slot canyon has depth-to-width ratios that typically exceed 10:1 over most of its length and can approach 100:1.
Look from Paria View to a valley in Bryce Canyon, Utah, with very striking shoulders. Depending on the topography, the rock types, and the climate, a variety of transitional forms between V-, U- and plain [clarification needed] valleys can form. The floor or bottom of these valleys can be broad or narrow, but all valleys have a shoulder.
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km (3 mi), from canyon floor to canyon rim, as with the Great Bahama Canyon.
