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.

The Grand Staircase is an immense sequence of sedimentary rock layers that stretch south from Bryce Canyon National Park through Zion National Park and into the Grand Canyon. Within this sequence, the oldest exposed formation in the Zion and Kolob canyons area is the youngest exposed formation in the Grand Canyon —the Kaibab limestone . [ 2 ]
Brady Canyon is a cliff-forming gray limestone with some chert. Wood Ranch is a slope-forming pale red and gray siltstone and dolomitic sandstone. An unconformity marks the top of this formation. One of the highest, and therefore youngest, formations seen in the Grand Canyon area is the Kaibab Limestone (see 6d in figure 1).
The Grand Canyon [a] is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
The Red River Gorge is a canyon system on the Red River in east-central Kentucky, United States.Geologically it is part of the Pottsville Escarpment.. The gorge lies within the Daniel Boone National Forest and was subsequently designated the Red River Gorge Geological Area, an area of around 29,000 acres (12,000 ha; 120 km 2; 45 sq mi). [1]
The Colorado Plateau which includes the Grand Canyon is the result of broad tectonic uplift followed by river erosion. [ 4 ] When mountains rise slowly, either due to orogenic uplift or other processes (e.g., rebound after glaciation ), an unusual feature known as a water gap may occur.
Canada is a beautiful country and an outdoors lover's paradise, with national parks such as Banff and amazing winter sports in Whistler.. But outside Quebec and a handful of other provinces ...
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.
