The first blasting was executed on July 25, 1904, and on July 4, 1905, the access to the gorge was inaugurated. On September 23, 1995, at 6:00 a.m. a massive rockfall occurred, causing 50,000 cubic metres (1,800,000 cu ft) of rock and debris to slide into the gorge. Subsequently, 300,000 m³ of water were dammed up 30 metres (98 ft) high.
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.

The Partnach Gorge. The Partnach Gorge (German: Partnachklamm) is a deep gorge that has been incised by a mountain stream, the Partnach, in the Reintal valley near the south German town of Garmisch-Partenkirchen. The gorge is 702 metres (2,303 ft) long and, in places, over 80 metres (260 ft) deep. It was designated a natural monument in 1912.
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.
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 ...
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.

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 predominant northern currents function as sedimentary ducts, along which there is an intensification of the particle transport processes between the coastal zone and the deep sea domain, making the transport of particulate matter (sediments) throughout the entire canyon very efficient. [5] This underwater gorge causes major changes in the ...
