A cataract is an opacity in the lens of the eye or its capsule.
Cataract also may refer to:
The Grand Canyon 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.
A canyon, 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. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
Victoria Falls is a waterfall on the Zambezi River, located on the border between Zambia and Zimbabwe. It is one of the world's largest waterfalls, with a width of 1,708 m (5,604 ft). The region around it is inhabited by several species of plants and animals.
Blackwater or Black Water may refer to:
The Cataract Gorge is a river gorge in Launceston, Tasmania, Australia, approximately 1.5 km from the city centre. It is one of the region's premier tourist attractions with a Cataract Gorge boat trip leaving from Home Point Parade. It is found at the lower section of the South Esk River.
The Todgha Gorges are a series of limestone river canyons, or wadi, in the eastern part of the High Atlas Mountains in Morocco, near the town of Tinerhir. Both the Todgha River, and the neighbouring Dadès River are responsible for carving out these deep cliff-sided canyons, on their final 40 kilometres (25 mi) through the mountains. The height of the canyon walls can vary, but in some places can be up to 400 metres (1,312 ft) high.
The known human history of the Grand Canyon area stretches back 10,500 years, when the first evidence of human presence in the area is found. Native Americans have inhabited the Grand Canyon and the area now covered by Grand Canyon National Park for at least the last 4,000 of those years. Ancestral Pueblo peoples, first as the Basketmaker culture and later as the more familiar Pueblo people, developed from the Desert Culture as they became less nomadic and more dependent on agriculture. A similar culture, the Cochimi also lived in the canyon area. Drought in the late 13th century likely caused both groups to move on. Other people followed, including the Paiute, Cerbat, and the Navajo, only to be later forced onto reservations by the United States Government.
Charyn Canyon, also known as the Sharyn Canyon is a canyon on the Charyn River in Kazakhstan. It is located about 200 km (120 mi) east of Almaty, close to the Kazakh–Chinese border. The canyon is roughly 154 km (96 mi) in length. It is part of the Charyn National Park established on 23 February 2004 and is located within the territory of the Uygur, Raiymbek, and Enbekshikazakh Districts of the Almaty Region. The canyon features many formations formed by the weathering of sedimentary rock. Though it is much smaller than the Grand Canyon, it has been described as being equally impressive.
A rift is a linear zone where the lithosphere is being pulled apart.
The Gorge can refer to the following:
Grand Canyon most often refers to:
The Gorge Amphitheatre, originally known as Champs de Brionne Music Theatre and commonly referred to as The Gorge, is an outdoor concert venue in Grant County, Washington, United States. It is situated near the Columbia River in Central Washington, nine miles (14 km) west of George. The venue is managed by Live Nation.
The Klickitat Trail is a 31-mile (50 km) rail trail along the Klickitat River in southern Washington in the Columbia River Gorge. The cycling and hiking trail offers river and canyon views throughout its length. It follows an old railroad corridor that at one time linked the towns of Lyle and Goldendale.
Henry Stanford Diltz is an American folk musician and photographer who has been active since the 1960s.
Cataract Canyon is a 46-mile-long (74 km) canyon of the Colorado River located within Canyonlands National Park and Glen Canyon National Recreation Area in southern Utah. It begins at Colorado's confluence with the Green River, and its downstream terminus is the confluence with the Dirty Devil River. The lower half of the canyon is submerged beneath Lake Powell when the lake is at its normal high water elevation of 3,700 feet (1,100 m).
A canyon, cañon or gorge is a geographical feature.
Major Powell was a 3-ton, twin-screw-driven steamboat built and launched in 1891 on the Green River at Green River, Utah, in August 1891.
The Cataract House was a hotel in the neighborhood of Buffalo Avenue in Niagara Falls, New York. The hotel was established in 1825 but destroyed by fire in 1945. It was a major stop on the Underground Railroad and it was the largest hotel in Niagara Falls. The hotel's name refers to the large and powerful waterfall next to property.
A gorge or canyon is a deep cleft resulting from weathering and the erosive activity of rivers.
