The Thomsen River, located in the Northwest Territories of Canada, is the northernmost usable river of the country. It is famous for canoeing.
The Northwest Territories is a federal territory of Canada. At a land area of approximately 1,144,000 km2 (442,000 sq mi) and a 2011 population of 41,462, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of 2016 is 44,291. Yellowknife became the territorial capital in 1967, following recommendations by the Carrothers Commission.
Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border. Its capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra. Consequently, its population is highly urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies widely across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons.
A canoe is a lightweight narrow vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel using a single-bladed paddle.
It flows across Banks Island in the Canadian Arctic Archipelago, and flows northward through Aulavik National Park before it empties through the Castel Bay into the M'Clure Strait (part of the Viscount Melville Sound of the Arctic Ocean).
Banks Island is one of the larger members of the Canadian Arctic Archipelago. Situated in the Inuvik Region, and part of the Inuvialuit Settlement Region, of the Northwest Territories, it is separated from Victoria Island to its east by the Prince of Wales Strait and from the mainland by Amundsen Gulf to its south. The Beaufort Sea lies to its west, and to its northeast M'Clure Strait separates the island from Prince Patrick Island and Melville Island.
Aulavik National Park is a national park located on Banks Island in the Northwest Territories of Canada. It is known for its access to the Thomsen River, one of the most northerly navigable rivers in North America. The park is a fly-in park, and protects approximately 12,274 square kilometres (4,739 sq mi) of Arctic Lowlands at the northern end of the island. The most practical way to visit the park is to charter a plane, and currently the park has four landing sites. Aulavik is considered a polar desert and often experiences high winds. Precipitation for the park is approximately 300 mm (12 in) per year. In the southern regions of the park a sparsely vegetated upland plateau reaches a height of 450 m (1,480 ft) above sea level.
The Thomsen River on northern Banks Island has been described as the most northerly multi-species river in North America. At least three fish species, lake trout (Salvelinus namaycush), least cisco (Coregonus sardinella), and ninespine stickleback (Pungitius pungitius), reach their known northern limit of distribution in the Thomsen River while the Arctic char (Salvelinus alpinus) is a common species. Lake whitefish (Coregonus clupeaformis) may also occur in upper reaches of the Thomsen and marine fourhorn sculpin (Myoxocephalus quadricornis) are occasionally found in the lower reaches of the river.Approximately one half of the Thomsen River watershed lies within Aulavik National Park.
Lake trout is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush,lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called mud hens.
Coregonus sardinella, known as the sardine cisco, and in North America as the least cisco, is a fresh- and brackishwater species of salmonid fish that inhabits rivers, estuaries and coastal waters of the marginal seas of the Arctic Basin, as well as some large lakes of those areas.
The ninespine stickleback, also called the ten-spined stickleback, is a freshwater species of fish in the family Gasterosteidae that inhabits temperate waters. It is widely but locally distributed throughout Eurasia and North America. Despite its name, the number of spines can vary from 8 to 12.
Victoria Island is a large island in the Canadian Arctic Archipelago that straddles the boundary between Nunavut and the Northwest Territories of Canada. It is the eighth largest island in the world, and at 217,291 km2 (83,897 sq mi) in area, it is Canada's second largest island. It is nearly double the size of Newfoundland (111,390 km2 [43,008 sq mi]), and is slightly larger than the island of Great Britain (209,331 km2 [80,823 sq mi]) but smaller than Honshu (225,800 km2 [87,182 sq mi]). It contains the world's largest island within an island within an island. The western third of the island belongs to the Inuvik Region in the Northwest Territories; the remainder is part of Nunavut's Kitikmeot Region.
Ukkusiksalik National Park is a national park in Nunavut, Canada. It covers 20,885 square kilometres (8,064 sq mi) of tundra and coastal mudflats south of the Arctic Circle and the hamlet of Repulse Bay, from Hudson Bay's Roes Welcome Sound towards the western Barrenlands and the source of Brown River. The park surrounds Wager Bay, a 100 kilometres (62 mi)-long inlet on the Hudson Bay. Although the smallest of Nunavut's four national parks, it is the sixth largest in Canada. Its name relates to steatite found there: Ukkusiksalik means "where there is material for the stone pot".
Arctic char or Arctic charr is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. Its distribution is circumpolar. It spawns in fresh water and populations can be lacustrine, riverine or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fished extensively. In Siberia, it is known as golets and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char in Elgygytgyn Lake.
Sachs Harbour is a hamlet located in the Inuvik Region of the Northwest Territories, Canada. Situated on the southwestern coast of Banks Island in the Inuvialuit Settlement Region, the population according to the 2011 census count was 103 people. The two principal languages in the town are Inuinnaqtun (Inuvialuktun) and English. The traditional name for the area is "Ikahuak", meaning "where you go across to". Bulk supplies of food and other items are brought by barge in the summer months and flights from Inuvik, some 325 mi (523 km) to the southwest, operate all year, via the Sachs Harbour Airport. Sachs Harbour is the only permanent settlement on Banks Island.
The broad whitefish is a freshwater whitefish species. Dark silvery in colour, and like a herring in its shape, its distinctive features include a convex head, short gill rakers, and a mild overbite. It is found in the Arctic-draining streams, lakes, and rivers of far eastern Russia and North America. Its prey includes larval insects, snails, and shellfish. It is eaten by humans and brown bears.
Lake Hazen is often called the northernmost lake of Canada, in the northern part of Ellesmere Island, Nunavut, but detailed maps show several smaller lakes up to more than 100 km (62 mi) farther north on Canada's northernmost island. Turnabout Lake is immediately northeast of the northern end of Hazen lake. Still further north are the Upper and Lower Dumbell Lakes, with Upper Dumbell Lake 5.2 km (3 mi) southwest of Alert, Canada's northernmost settlement on the coast of Lincoln Sea, Arctic Ocean.
The Peary caribou is a subspecies of the reindeer found in the High Arctic islands of Nunavut and the Northwest Territories in Canada. They are the smallest of the North American caribou, with the females weighing an average of 60 kilograms (130 lb) and the males 110 kilograms (240 lb). In length the females average 1.4 m (4.6 ft) and the males 1.7 m (5.6 ft).
The Northwest Territories is a territory in Northern Canada, specifically in Northwestern Canada between Yukon Territory and Nunavut including part of Victoria Island, Melville Island, and other islands on the western Arctic Archipelago. Originally a much wider territory enclosing most of central and northern Canada, the Northwest Territories was created in 1870 from the Hudson's Bay Company's holdings that were sold to Canada from 1869-1870. In addition, Alberta and Saskatchewan were formed from the territory in 1905. In 1999, it was divided again: the eastern portion became the new territory of Nunavut. Yellowknife stands as its largest city and capital. It has a population of 42,800 and has an area of 532,643 sq mi (1,379,540 km2). The current territory lies west of Nunavut, north of latitude 60° north, and east of Yukon.
Qamanirjuaq Lake is a lake in Kivalliq Region, Nunavut, Canada. It is the first of several named lakes on the eastward flow of the Ferguson River through the eastern barrenlands. The lake is located about 1 mile (2 km) downstream from Ferguson Lake, and adjacent upstream to Parker Lake South. The Ferguson River passes through a series of rapids before entering the western arm of Qamanirjuaq Lake.
Mercy Bay is a Canadian Arctic waterway in the Northwest Territories. It is a southern arm of M'Clure Strait on northeast Banks Island. The mouth of Castel Bay is less than 20 kilometres (12 mi) to the west. These bays are a part of Aulavik National Park.
Castel Bay is a Canadian Arctic waterway in the Northwest Territories. It is a southern arm of M'Clure Strait on northeast Banks Island. The mouth of the larger Mercy Bay is less than 20 km (12 mi) to the east. These bays are a part of Aulavik National Park.
Hornaday River is a waterway located above the Arctic Circle on the mainland of Northern Canada.
The Ruggles River is a waterway in Qikiqtaaluk Region, Nunavut, Canada. It is located within Ellesmere Island's Quttinirpaaq National Park. The river is the only outflow for Lake Hazen. It flows southeast to Chandler Fiord and out to Lady Franklin Bay.
A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
