Alberta, British Columbia, Manitoba, Saskatchewan, Yukon Territory
The mountains of the west coast, incorporating British Columbia and the Yukon Territory, descend into the vast, flat prairies of Alberta, Saskatchewan, and Manitoba. The empty lands and fertile soils of the prairie provinces attracted migrants, and the descendants of early European immigrants still make up a large proportion of the population. The mechanization of agriculture has reduced the need for labor, and rural population densities remain low.
The majority of the people live within 100 miles (160 km) of the southern Canada–US border, and in British Columbia, one of the leading Canadian provinces in terms of economic wealth.
The Yukon Territory, in the far north, remains a relatively unspoiled wilderness, containing large, untapped mineral reserves. This province has a significant population of Native American people, many of whom maintain a traditional lifestyle.
The landscape of the western Canadian provinces
The massive Rocky Mountains form a continental divide between rivers flowing eastward and westward. The interior plains lie east of the mountains, stretching from the Arctic Circle south into the US. Covered with glacial deposits from the last Ice Age, these interspersed with hilly regions and long, steep escarpments.
Interesting facts of the western Canadian provinces
- Mount Logan rises 19,551 ft (5959 m). It is the highest peak in Canada.
- The Columbia Icefield in the Rocky Mountains is the source of two major rivers, the Athabasca and the North Saskatchewan.
- The badlands of Alberta created when east-flowing rivers, swollen by meltwater at the end of the last Ice Age, cut deep, wide canyons producing eroded, barren landscapes.
- Braided rivers are shallow and fast-flowing. The interlaced branches formed when excess sediments, which can no longer be transported, are deposited. The sediments collect in the river channel forming bars and sand flats. Islands form when the bars colonized by vegetation.
- The Rocky Mountain Trench is the longest linear fault in the world. It has formed a straight, flat-bottomed valley between 2–9 miles (4–15 km) wide, and up to 3280 ft (1000 m) deep.
- Hundreds of islands dot the fjord-indented coast of British Columbia; the largest is Vancouver Island.
- Three major passes cut through the Rocky Mountains: Yellowhead, Kicking Horse, and Crowsnest. They are all used as transportation routes through the mountains.
- The Cypress Hills rise to 4806 ft (1465 m) above the surrounding plain. Having escaped the last glaciation, they contain unique plant and animal life. The silvery lupine, bunchberry, and lodgepole pine all grow in the cool, moist climate of the hills.
- The Alberta and Saskatchewan plains bear strong testament to past glaciations. The Assiniboine, Saskatchewan and Qu’Appelle rivers occupy flat-bottomed, steep-sided valleys eroded during the last Ice Age by glacial meltwater.
- The lowlands of Manitoba are a basin that once held the vast post-glacial Lake Agassiz, remnants of which include Lake Winnipeg, Lake Winnipegosis, and Lake Manitoba.
- The Nelson and Churchill rivers drain northward across the Canadian Shield to Hudson Bay. The shield covers three-fifths of Saskatchewan.
Transportation & industry in the western Canadian provinces
The western provinces contain a wealth of mineral resources. Alberta holds the bulk of Canada’s fossil fuels; the other provinces contain reserves of metallic ores, such as zinc, lead, and silver. Isolation from markets has slowed the development of manufacturing, restricting it to large cities like Vancouver, Winnipeg, and Calgary. Hydroelectric power is widely exploited, although there is increasing concern about potential ecological damage.
Using the land & sea in the western Canadian provinces
Wheat farming is the economic mainstay of Alberta, Manitoba, and Saskatchewan, which contain 82% of farmland in Canada. Cattle also raised on the prairies. Forestry and fishing are the most prominent resource-based industries in British Columbia. Despite the mountainous terrain, fruit and specialized grains can grow in the Okanagan and Fraser valleys.
