Monkman Pass, 1061 m (3481 ft), is a mountain pass in the Canadian Rockies, located southwest of the coal-mining town of Tumbler Ridge, British Columbia.
 Located in the Hart Ranges, it is sometimes reckoned as the southern limit of the informal grouping known as the Northern Rockies, although those are sometimes reckoned as extending farther southeast to Mount Ovington and even to Mount Robson.
 Located on the Continental Divide, it is lower than the Yellowhead and Pine Passes.
 In 1937-39, a proposal to build a highway through the route led to a survey exploration, but the route was not completed.
 A highway access from other parts of British Columbia to the Peace Country was not made until much later, with the construction of the John Hart Highway through the Pine Pass; the route is now the Monkman Pass Historical Trail, built in 2006-07 and opened in 2008.
 The pass is at the head of the Murray River and south of the height of land at the head of the Parsnip River, and was discovered by accident by its namesake, Peace River Country fur trapper Alexander Monkman in 1922 who crossed it by sled and dogs.
The Montana Dinosaur Trail is a series of fourteen dinosaur-themed museums, state parks and other attractions in twelve communities located in the central and eastern regions of the state of Montana in the United States of America.
 The trail, a plan to increase attendance at the region's museums and drive tourism in general was established via the work of a number of museums as well as community and state officials.
 The idea for a trail uniting the museums and promoting tourism in eastern Montana came from a meeting of the Missouri River Country board of directors at the Dinosaur Field Station in Malta, Montana and the trail was officially launched via the efforts of the tourism groups of: Custer Country, Missouri River Country, Russell Country and Yellowstone Country; two state agencies: Fish, Wildlife and Parks and Travel Montana; and two federal agencies: the Army Corps of Engineers and the Bureau of Land Management.
Gangavalli River is one of the many small rivers that originates and flows entirely within the western part of state of Karnataka in India.
 The National Highway 17 (India) continues on the Hosur Bridge the bridge built over Gangavali River and the road continues to split the Ankola and Kumta regions to connect Uttar Kannada district to Dharwar and Mangalore area.
O'Donnel River is a river located in the Atlin Country region of British Columbia.
 This river flows into the east side of Atlin Lake about 14 mi south of the town of Atlin.
 The river is about 30 mi long.
 The river was discovered in 1898 and was originally known as Moose River or Caribou River.
 In 1912 a rich gold streak was discovered in the river, which attracted many miners.
 The river has been sluiced, drifted, and hydraulicked.
The tallest dams in China are some of the tallest dams in the world.
 Nearly 22,000 dams over 15 m in height – about half the world's total – have been constructed in China since the 1950s.
 Many of the tallest are located in the southwestern part of the country (Guizhou, Sichuan, Yunnan) on rivers such as the Mekong, the Yangtze, and its upper stretch (Jinsha River) and tributaries (Yalong, Dadu, Min and Wu).
 The Yellow River in the western part of the country also hosts several among the tallest.
 Purposes for these high structures include flood control, irrigation and, predominantly, hydroelectric power.
 While beneficial, many throughout the country have been criticized for their effects on the environment, displacement of locals and effect on transboundary river flows.
 Currently, the country's and world's tallest, Jinping-I Dam, an arch dam 305 m high, is located in Sichuan.
 The tallest embankment dam in China is the 261 m Nuozhadu Dam in Yunnan.
 The country's highest gravity dam is Longtan Dam at 216.2 m , which can be found in Guangxi.
 At 233 m , Shuibuya Dam in Hubei is the world's tallest concrete-face rock-fill dam.
 In Sichuan, the government is constructing the 312 m tall Shuangjiangkou Dam which, when complete, will become the world's tallest dam.
Skjern River (Danish: "Skjern Å" ) is the largest river in Denmark, in terms of volume.
 The river has its spring in Tinnet Krat in central Jutland, very close to Gudenå, another large river.
 It drains about one tenth of Denmark and discharges 206 m³/s (89,100 ft³/s) of water into the Ringkøbing Fjord - a lagoon and former bay of the North Sea.
 The river has its name from town of Skjern, located at the river delta (the only river delta in the country) at Ringkøbing Fjord.
Tranquille River is a river located in the Thompson Country region of British Columbia.
 The river is located on the north side of Kamloops Lake almost 8 mi west of Kamloops, near Tranquille, Kamloops.
 The river was discovered as gold-bearing in 1852.
 The river has been mined and the total value of gold mined is estimated at $250,000.
The Nata River or Manzamnyama River is a natural watercourse in Southern Africa.
 It is an ephemeral river flowing in Zimbabwe and Botswana.
 It has a length of 330 km from its source to mouth, 210 km in Zimbabwe and 120 km in Botswana.
 Its total catchment area is 24,585 km.
 The river originates in Sandown (S20.425036˚, E28.180660˚), a small farming town located on the Zimbabwean central watershed 50 km south west of Bulawayo and ends in the Makgadikgadi Pans (S20.348816˚, E26.240166˚) in Botswana.
 There is no outlet from the salt pans which can be considered as the “dead sea” of the south.
 The upper reaches of the river are located in a commercial farming area where good environmental and farming practices have resulted in the river experiencing very little siltation/sedimentation.
 Impressive sedimentation starts occurring about 65 km along the river course marking the beginning of a 90 km stretch in Zimbabwe where the river passes through communal farming areas.
 It is on this stretch where the sand-abstraction potential of the river is realised and communities rely on the sand river water for domestic, farming and livestock purposes.
 Within the country of Botswana the Nata River is a source of water to the ephemeral wetlands of the Makgadikgadi Pans, where a number of species of limited distribution thrive.
 Specifically the Nata River discharges to Sua Pan, draining parts of eastern Botswana and southwestern Zimbabwe.
The Middle River, or in the Carrier language (Dakelh) Dzitl'ainli Koh, is a river in the Omineca Country of the northwestern Central Interior of British Columbia, Canada, flowing southeast from the outlet of Takla Lake into Trembleur Lake over a distance of approximately 35 km .
 The river is part of the route of the Stuart River-Takla Lake salmon run, which comes up the Fraser River via its tributaries the Nechako and Stuart Rivers and terminates at Takla Lake, and the route of the unfinished Dease Lake Extension of the British Columbia Railway runs along the river's left (north) bank.
 The community of Middle River, including the Dzitline Lee Indian Reserve 9.
 O K'Ay Wha Cho 26, another Indian Reserve, is located on the west bank of the river between Takla and Trembleur Lakes.
Mangalore, officially known as Mangaluru, is the chief port city of the Indian state of Karnataka.
 It is known as "Kudla" in Tulu, "Kodial" in Konkani, "Maikāla" in Beary, "Mangaluru" in Kannada and "Mangalapuram" in Malayalam.
 It is located about 352 km west of the state capital, Bengaluru between the Arabian Sea and the Western Ghat mountain ranges.
 It is the administrative headquarters of the Dakshina Kannada district.
 It developed as a port on the Arabian Sea—remaining, to this day, a major port of India.
 Lying on the backwaters of the Netravati and Gurupura rivers, Mangalore is often used as a staging point for sea traffic along the Malabar Coast.
 The city has a tropical climate and lies in the path of the Arabian Sea branch of the South-West monsoons.
 Mangalore's port handles 75 per cent of India's coffee and cashew exports.
 Mangalore was ruled by several major powers, including the Kadambas, Alupas, Vijayanagar Empire, Keladi Nayaks and the Portuguese.
 The city was a source of contention between the British and the Mysore rulers, Hyder Ali and Tipu Sultan.
 Eventually annexed by the British in 1799, Mangalore remained part of the Madras Presidency until India's independence in 1947.
 The city was unified with the state of Mysore (now called "Karnataka") in 1956.
