Geography of Northwest Territories


Geography of Northwest Territories

The Thelon River
The Geography of 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.[1] 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 would be sold to Canada from 1869-1870.[1] In addition, Alberta and Saskatchewan were formed from the territory in 1905. When in 1999, it was divided again, having the eastern portion becoming the new territory of Nunavut.[1] Yellowknife stands as its largest city and capital.[1] It has a population of 42,800[1] and has an area of 532,643 sq mi (1,379,540 km2). It lies west of Nunavut, north of latitude 60° north, and east of Yukon.

It stretches across the top of the North American continent, reaching into the Arctic Circle.[1] The region consists of the following: many islands, such as Victoria Island, the Mackenzie River, and Great Bear and Great Slave lakes. Over half the people are Inuit and First Nations peoples. In the 18th century, the main land was explored by Samuel Hearne for the Hudson's Bay Company and by Alexander Mackenzie.[1] European settlers mainly were whalers, fur traders, and missionaries up until the 1920s, when oil was discovered and as the territorial administration had formed.[1] Their principal industry is mining and centers of the petroleum and Natural Gas fields in the western Arctic coastal regions.[1]

History and founding

As European Incursions began in the region, they encountered the fishing and hunting Inuit and Dene. Vikings who came from Greenland may be the first Europeans to explore the eastern section of the Northwest Territories now Nunavut.[1] Sir Martin Frobisher was the first of a long line of explorers to venture the Northwest Passage. Although, it was Henry Hudson that discovered the gateway to the Northwest (Hudson Bay) in 1610.[1]

For several decades the Hudson's Bay Company sent trade-explorers into the northern sea lanes and along the coast; in 1771, Samuel Hearne went from Hudson Bay and descended the Coppermine River. By 1789, exploring for the North West Company, Alexander Mackenzie ventured to the mouth of the Mackenzie River. Sir John Franklin contributed scientific expeditions to the Arctic Northwest in the first half of the Nineteenth century, gaining valuable geographic data.[1]

The area of present Northwest Territories and Nunavut was part of the large islands sold by the Hudson's Bay Company to the new Canadian confederation in 1870.[1] Some of those lands were joined to the provinces of Ontario and Quebec. Then, the province of Manitoba was formed from them in 1870, and Alberta and Saskatchewan in 1905, all south of 60°North. In 1898, the Yukon Territory had been separated. The boundaries of the Northwest Territories were set in 1912 and stayed fixed until Nunavut was created in 1999.

Ever since the 1982 patriation of the Canadian Constitution, several land claims were made by native peoples having made their ways through the courts and federal government.[1] In 1992, the residents of the Northwest Territories voted to divide the territory along ethnic lines, with the Inuit on the east and the Dene to the west. The novel territory of Nunavut, dominated by the Inuit, came into existence on April Fools' Day, 1999. This split the Northwest Territories along a ziz-zag path running from the Saskatchewan-Manitoba border through the Arctic Archipelago on the North Pole. Other native peoples with claim were the Métis and the Inuvialuit. Joe Handley became the Territories' premier in December 2003.

Communication and travel

In the Northwest Territories, transportation and communication can be complex.[1] Long winters tend to close the rivers navigation for nearly two months of the year.[1] Contrary to the Great Slave Railway and Mackenzie highway system, that links to Alberta and to the Great Slave area, commerce, supply, and travel remain to be largely airborne.[1] The region includes scores of airfields.[1] An ongoing northern roads program, launched since 1966, helps opening up the area. Moreover, the Liard Highway, opened in 1984, connects Fort Simpson to the Alaska Highway.[1] Other highways link Inuvik to the Yukon and Hay River then Yellowknife to the highways in Alberta. In winter, some frozen rivers and lakes are useful for road traffic.[1] These are also vast telecommunication services.[1]

People and the land

Geographically, the area is mainly south of the tree line, which runs roughly northwest to southeast, from the Mackenzie River delta in the Arctic Ocean into the Southeastern corner of the territory.[1] Tundra is characteristic of the land north of the tree line; there the native people depend on hunting, arts and crafts making for an income fur-trapping, and obtaining many sources through fish, seals, reindeer, and caribou.[1] The majority of the development in this area takes place south of the tree line, where the land is covered with soft woods and rich minerals.[1] Also, two of the world's largest lakes (Great Slave and Great Bear) are located here. Great Slave Lake is the source of one of the world's longest rivers, the Mackenzie, that runs 1,120 miles(1,800 km) to its outlet at the Arctic Ocean.[1] The Northwest Territories is the site of the northern end of Wood Buffalo National Park (est. 1922) and all of the Nahanni National Park (est. 1972).[1]


The Northwest Territories contains the Mackenzie dike swarm, which is the largest dike swarm known on Earth.[2] At ca. 1.269-1.267 Ga, the Slave craton was partly uplifted and intruded by the giant Mackenzie dyke swarm, radiating from a mantle plume center west of Victoria Island. This is the last major event affecting the core of the Slave craton, although some younger mafic magmatic events affect its edges.


Agriculture of the Northwest Territories is nearly impossible except for limited cultivation south of the Mackenzie River area.[1] Trapping, stands as the regions oldest industry, which ranks second following mining.[1] Another thriving industry is fishing, based on lake trout and whitefish, is centered on the village of Hay River, on Great Slave Lake. Minerals are currently the Territories' most valuable natural resource.[1] Oil is to be pumped and refined at Tulita (formerly Fort Norman) and Norman Wells on the Mackenzie River. Copper is extracted on the Coppermine River. Diamonds and Gold are currently produced in increasing amounts.[1] The region also includes tungsten, silver, cadmium, and nickel.

Significant hydroelectric developments are on the Talston and Snare rivers.[1]



The territory is governed through a 19-member Legislative Assembly which elects a premier and cabinet; an appointed commissioner holds a position similar to that of a Canadian lieutenant governor. The territory sends one Senator and one Member of Parliament to the Parliament of Canada.[1]
