Concept
Geography of Saskatchewan
Résumé
The geography of Saskatchewan is unique among the provinces and territories of Canada in some respects. It is one of only two landlocked regions (Alberta is the other) and it is the only region whose borders are not based on natural features like lakes, rivers, or drainage divides. The borders of Saskatchewan, which make it very nearly a trapezoid, were determined in 1905 when it became a Canadian province. Saskatchewan has a total area of of which is land and is water.
The province's name comes from the Saskatchewan River, whose Cree name is: kisiskatchewani sipi, meaning "swift flowing river".
Saskatchewan can be divided into three regions: grassland (part of the Great Plains) in the south, aspen parkland in the centre, and forest in the north. The forest region lies partly on the northern part of the Great Plains and partly on the Canadian Shield. Its principal rivers are the Assiniboine River, and North and South Saskatchewan Rivers.
Saskatchewan is bordered on the west by Alberta, on the north by the Northwest Territories, on the east by Manitoba, and on the south by the U.S. states of Montana and North Dakota.
Saskatchewan is very close to a trapezoid. Its western border runs concurrent with the 4th meridian or the 110°W longitude, separating Saskatchewan from the province of Alberta. This border extends in length for and was established in 1905 when both provinces were formed.
Saskatchewan's eastern border includes minor measurement errors from the 1880s, so that it does not lie perfectly on the 102°W longitude, but rather it is slightly west of that meridian from 60°N parallel to 55°47'N, then slightly east of that until the Canada–United States border – an irregular line (rather than a straight one) for its distance. When Saskatchewan was formed in 1905, Manitoba and the District of Keewatin were the neighbouring areas to the east. Manitoba was enlarged in 1912 north to the 60th parallel, becoming Saskatchewan's only eastern neighbour. This remaining section of the border was determined by survey between 1961 and 1972.
