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. [2]
Some sections of a stream or river valleys may have vertically incised their course to such an extent that the valley they occupy is best described as a gorge, ravine, or canyon. Rapid down-cutting may result from localized uplift of the land surface or rejuvenation of the watercourse as a result for example of a reduction in the base level to ...
Canyon / Gorge – Deep chasm between cliffs; Chine – Steep-sided river valley; Couloir – Steep, narrow mountain gully; Defile (geography) – Narrow pass or gorge between mountains or hills; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Mountain pass – Route through a mountain range or over a ...
The lower 57.2 miles (92.1 km) is known as the Little Colorado River Gorge [3] and forms one of the largest arms of the Grand Canyon, at over 3,000 feet (910 m) deep where it joins the Colorado near Desert View in Grand Canyon National Park. An overlook of the gorge is a Navajo Nation Tribal Park.
A ravine is a landform that is narrower than a canyon and is often the product of streambank erosion. Ravines are typically classified as larger in scale than gullies, although smaller than valleys. [1] Ravines may also be called a cleuch, dell, ghout , gill or ghyll, glen, gorge, kloof (South Africa), and chine (Isle of Wight)
Canyon – Deep chasm between cliffs, includes gorge. Dale (landform) – Open valley; Coulee – Type of valley or drainage zone; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Ravine – Small valley, often due to stream erosion; Valley – Low area between hills, often with a river running through it
The canyon has a length of about 240 kilometres (150 mi) as the gorge bends around Mount Namcha Barwa (7,782 metres or 25,531 feet) and cuts its way through the eastern Himalayas. Its waters drop from about 2,900 metres (9,500 ft) near Pei to about 1,500 metres (4,900 ft) at the end of the Upper Gorge where the Po Tsangpo River enters.
The Royal Gorge is a canyon of the Arkansas River located west of Cañon City, Colorado.The canyon begins at the mouth of Grape Creek, about 2 mi (3.2 km) west of central Cañon City, and continues in a west-northwesterly direction for approximately 6 mi (9.7 km) until ending near U.S. Route 50.
