The Canadian Shield, also called the Laurentian Plateau, is a large area of exposed Precambrian igneous and high-grade metamorphic rocks that forms the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which the composition of igneous rock resulting from long volcanic history is frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the Shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the United States. Human population is sparse and industrial development is minimal, but mining is prevalent.
Lake Athabasca is located in the northwest corner of Saskatchewan and the northeast corner of Alberta between 58° and 60° N. The lake is 26% in Alberta and 74% in Saskatchewan.
Carswell is an impact crater within the Athabasca Basin of the Canadian Shield in northern Saskatchewan, Canada. It is 39 kilometres (24 mi) in diameter and the age is estimated to be 115 ± 10 million years. The crater is exposed at the surface.
Lac Couture is a lake in Northern Quebec, Canada. It is located near Hudson Bay in the Kativik territory. The lake is approximately 150 meters deep.
Gow is an impact crater in Saskatchewan, Canada.
Maple Creek is a subterranean meteorite crater in Saskatchewan, Canada. It is 6 km (3.7 mi) in diameter and the age is estimated to be less than 75 million years. The crater is buried beneath younger sediments and cannot be seen at the surface.
Mistastin crater is a meteorite crater in Labrador, Canada which contains the roughly circular Mistastin Lake. The lake is approximately 16 km (9.9 mi) in diameter, while the estimated diameter of the original crater is 28 km (17 mi). The age of the crater is calculated to be 36.6 ± 2 million years (Eocene).
Viewfield is an impact crater in Saskatchewan, Canada.
Reindeer Lake is a lake in Western Canada located on the border between northeastern Saskatchewan and northwestern Manitoba, with the majority in Saskatchewan. The name of the lake appears to be a translation of the Algonquian name. It is the 24th largest lake in the world by area, as well as being the second-largest lake in Saskatchewan and the ninth largest in Canada. 8% of the lake lies in Manitoba and 92% of lake in Saskatchewan.
Skeleton Lake is a lake in the municipalities of Huntsville and Muskoka Lakes in the District Municipality of Muskoka, Ontario, Canada, about 17 kilometres (11 mi) west of the town centre of Huntsville. Up until 1991, the Ministry of Natural Resources operated a fish hatchery on the lake.
The Slate Islands archipelago is formed of two main islands, five minor islands and numerous islets located in northern Lake Superior, 10 kilometres (6 mi) south of the town of Terrace Bay. The islands were created by a meteorite impact which formed a crater about 32 km (20 mi) wide. In 1985, the Ontario government established the Slate Islands as a natural environment provincial park. The islands are notable for having Ontario's largest herd of boreal woodland caribou.
The Manicouagan or Manicuagan River, often clipped to Manic, is a river in Côte-Nord region of Quebec, Canada. The river originates in the Manicouagan Reservoir and flows approximately 200 kilometres (120 mi) south, emptying into the Saint Lawrence River near Baie-Comeau. The reservoir, also known as Lake Manicouagan, lies within the remnant of an ancient eroded impact crater (astrobleme). It was formed following the impact of a 5 kilometres (3.1 mi) diameter asteroid which excavated a crater originally about 100 km (62 mi) wide, although erosion and deposition of sediments have since reduced the visible diameter to about 72 km (45 mi). The Manicouagan crater is the sixth-largest confirmed impact crater known on earth.
Denare Beach is a northern village on the east shore of Amisk Lake, Saskatchewan. Located on Highway 167, the community is 20 km (12 mi) southwest of Flin Flon and 422 km (262 mi) northeast of Prince Albert.
The Lac Wiyâshâkimî, also called the Clearwater Lakes in English, is a calque of Wiyâšâkamî in Northern East Cree and Allait Qasigialingat by the Inuit, are a pair of annular lakes on the Canadian Shield in Quebec, Canada, near Hudson Bay.
The geography of Saskatchewan is unique among the provinces and territories of Canada in some respects. It is one of only two landlocked regions 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 651,036 square kilometres (251,366 sq mi) of which 591,670 km2 (228,450 sq mi) is land and 59,366 km2 (22,921 sq mi) is water.
The Ottawa-Bonnechere Graben is a geological structure that coincides with a 55 km (34 mi) wide topographic depression extending from near Montréal through Ottawa. It is part of the Saint Lawrence rift system that also includes the seismically active Saguenay graben. This rift valley was formed when the Earth's crust moved downward about a kilometre between two major fault zones known as the Mattawa and Petawawa faults.
The geology of Saskatchewan can be divided into two main geological regions, the Precambrian Canadian Shield and the Phanerozoic Western Canadian Sedimentary Basin. Within the Precambrian shield exists the Athabasca sedimentary basin. Meteorite impacts have altered the natural geological formation processes. The prairies were most recently affected by glacial events in the Quaternary period.
Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude. It is 81.4 kilometres (50.6 mi) in diameter and contains about 2,200 cubic kilometres (530 cu mi) of water ice, comparable in volume to Great Bear Lake in northern Canada. The crater was named after Sergei Korolev (1907–1966), the head Soviet rocket engineer and designer during the Space Race in the 1950s and 1960s.
Hatchet Lake Dene Nation is a Dene First Nation in northern Saskatchewan. The main settlement, Wollaston Lake, is an unincorporated community on Wollaston Lake in the boreal forest of northeastern Saskatchewan, Canada.
The Tunnunik impact crater, formerly known as the Prince Albert Impact Crater, is a recently confirmed meteorite impact crater. It is located on Prince Albert Peninsula in the northwestern part of Victoria Island in Canada's Northwest Territories.
