Canyon. 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.

As the Vikos Gorge is a deep cross section of the mountain, its slopes expose a series of rock formations of various ages. The upper layers, at a depth of 0–200 m (660 ft), consist of relatively young Eocene limestone , at a depth of 200 m (660 ft)–700 m (2,300 ft) they consist of a stratum from the Campanian era, while below 700 m (2,300 ...
A concrete road continues up the valley, past the hotels at the mouth of the gorge all the way to the villages of Aït Hani, and Tamtatouchte. Thanks to its robust rock sides with many uneven surfaces, Todgha Gorge is popular among rock climbers. [2] More than 150 routes rated French Grade 5+ to 8 have been bolted in the canyon.

2,500 m 3 /s (88,000 cu ft/s) The Kosi or Koshi is a transboundary river which flows through China, Nepal and India. It drains the northern slopes of the Himalayas in Tibet and the southern slopes in Nepal. From a major confluence of tributaries north of the Chatra Gorge onwards, the Kosi River is also known as the Saptakoshi (Nepali ...
The gorge separates the major peaks of Dhaulagiri (8,167 m or 26,795 ft) on the west and Annapurna (8,091 m or 26,545 ft) on the east. The portion of the river directly between Dhaulagiri and Annapurna I (7 km or 4.3 mi downstream from Tukuche) is at an elevation of 2,520 m (8,270 ft), which is 5,571 m (18,278 ft) lower than Annapurna I. [4] As tectonic activity has forced the mountains higher ...
Rio Grande Gorge Bridge. Geologically, the Rio Grande Gorge is a canyon, [1] carved out by erosion over the last several million years. [2] The Rio Grande Gorge and its river follow a topographical low within the larger Rio Grande Rift; a mixture of volcanic activity, shifting tectonic plates, and erosion of layers of gravels and lava yielded the recognizable narrow, deep gorge visible today.
The Columbia River Gorge is a canyon of the Columbia River in the Pacific Northwest of the United States. Up to 4,000 feet (1,200 m) deep, the canyon stretches for over eighty miles (130 km) as the river winds westward through the Cascade Range, forming the boundary between the state of Washington to the north and Oregon to the south.
