Geography of Manitoba

The geography of Manitoba addresses the easternmost of the three prairie Canadian provinces, located in the longitudinal centre of Canada. Manitoba borders on Saskatchewan to the west, Ontario to the east, Nunavut to the north, and the American states of North Dakota and Minnesota to the south. Although the border with Saskatchewan appears straight on large-scale maps, it actually has many right-angle corners that give the appearance of a slanted line. In elevation, Manitoba ranges from sea level on Hudson Bay to 2727 ft (831 m) on top of Baldy Mountain. The northern sixty percent of the province is on the Canadian Shield. The northernmost regions of Manitoba lie permafrost (permanently frozen subsoil), and a section of tundra bordering Hudson Bay.

Map of Manitoba

All waters in the province flow into Hudson Bay, due to its coastal area. Lake Winnipegosis and Lake Winnipeg are two of its largest lakes. Important rivers are the Red River, Assiniboine River, Nelson River, and Churchill River. Manitoba is the sixth largest Canadian province, and the eighth largest Canadian province by percentage of fresh water. The capital and largest city of the province is Winnipeg; the province lies in the time zone UTC −6.

Environmental geography

Manitoba has an extreme climate, but southern latitudes allow agriculture. The northern area of the region ranges from coniferous forests to muskeg to tundra in the far north. Before settlement had occurred, a vast portion of southern Manitoba was either flood plain or swamp. An extensive system for drainage ditches was required throughout south-central Manitoba to make the region suitable for cultivation.

Boreal forests of the southern part of the province have extensive black spruce and white spruce forests. The tundra region of northern Manitoba exhibits more sparse black spruce forests whose tree heights are limited by the thin soils, permafrost underlayer and generally cold climate. In this region polar bears are found, denning in the Wapusk National Park and migrating to hunt for seals when pack ice forms on Hudson Bay.[1]

Historical geography

Manitoba is bordered on the east by Ontario, on the south by North Dakota and Minnesota, on the west by Saskatchewan, and on the north by Nunavut. Northeast Manitoba follows the Hudson Bay shoreline. Churchill, on the Hudson Bay is the only port for the prairie provinces. The harbour serves as an open market for grain.

Manitoba was the first Canadian province to be involved in the wheat industry. There are only three ice-free months a year that allow for the shipments to be sent when shipping through the home port of Churchill.

The Canadian Shield limits the amount of farming in the north, but there are some forestry and mining operations. The majority of the grain production is found in farms in the south.

Central and southern Manitoba is covered by lakes and rivers. Most of the population is centred in the southern third of the province.[3]

Manitoba played a significant role in the European settlement of the Canadian west. Explorers arrived in Manitoba by the Hudson Bay, in search of a passage to China. As the fur trade boomed, settlements rose up in the province to trading posts for the Natives and the voyageurs. The settlement was not easy, and colonization slowed down for several years around 1816. In 1870, the Hudson's Bay Company sold its huge domain to the confederation of Canada.

Settlement inflated in Manitoba when the railway was built in the province and again in late 19th, early 20th century when government promoted settlement by European immigrants.

Mountain ranges of Manitoba
Relief of Manitoba

Manitoba has two mountain/hill ranges, which are both escarpments formed by prehistoric Lake Agassiz: the Pembina Escarpment and the Manitoba Escarpment.

  • The Pembina Mountains are located in southern Manitoba and extend to the Assiniboine River and over North Dakota border. The highest point is 2,000 feet.
  • The Manitoba Escarpment has four different sets of mountains/hills, and three are in Manitoba: the Riding Mountains, the Duck Mountains, and the Porcupine Mountains.

The highest point in Manitoba is Baldy Mountain, which reaches 2,727 feet (832 m) and is located in the Duck Mountains.[4] Hart Mountain, which is located in the Porcupine Mountains, rises to 2,700 feet and is not far behind.

Geology

In central Manitoba lies the Flin Flon greenstone belt, which is one of the largest Paleoproterozoic volcanic-hosted massive sulphide districts in the world, containing 27 copper-zinc-(gold) deposits from which more than 183 million tonnes of sulphide have been mined.[5]
