ÃŽle Rouleau Crater
Île Rouleau is an impact crater in Baie-James, Quebec, Canada, located on a small, uninhabited island in Lake Mistassini in the centre of the province.

Lake Mistassini
Lake Mistassini () is the largest natural lake by surface area in the province of Quebec, Canada, with a total surface area of approximately and a net area (water surface area only) of . It is located in the Jamésie region of the province, approximately east of James Bay. The Cree town of Mistissini is located on Watson Peninsula in the south-east corner of the lake, which separates Baie du Poste from Abatagouche Bay. Extensive forests of spruce, birch, pine, and fir trees, which support a booming forestry industry, surround the lake. Significant tributaries flowing into the lake include: Chalifour, Pépeshquasati, Takwa, Témiscamie, and Wabissinane. Other nearby lakes include Lake Albanel and Lake Troilus. Etymology The name Mistassini came from the Cree or Montagnais , and means "large rock"; it probably refers to a large glacial erratic stone, about high, located near the outlet of Lake Mistassini into the Rupert River. Over the centuries, it went through man ...

Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ...

Quebec
Quebec is Canada's List of Canadian provinces and territories by area, largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Between 1534 and 1763, what is now Quebec was the List of French possessions and colonies, French colony of ''Canada (New France), Canada'' and was the most developed colony in New France.

Nord-du-Québec
Nord-du-Québec (; ) is the largest, but the least populous, of the seventeen administrative regions of Quebec, Canada. Spread over nearly 14 degrees of latitude, north of the 49th parallel, the region covers on the Labrador Peninsula, making it larger than Alberta, and slightly smaller than British Columbia or Ontario. It is just over half of the province's total land area. History Nord-du-Québec possesses 3,644 archaeological sites known and listed by the Ministère de la Culture, des Communications et de la Condition féminine (MCCCF), along La Grande Rivière basin, the Otish Mountains sector and in the coastal areas of Quaqtaq, near Ungava Bay. These sites are mostly of First Nations origin and bear witness to several thousands of years of occupation of the territory of the Cree and Inuit ancestors of the region. Before 1912, the northernmost part of this region was part of the Ungava District of the Northwest Territories, and until 1987 it was referred to as Nouve ...

Baie-James
The Baie-James () was a List of former municipalities in Quebec, former municipality in northern Quebec, Canada, which existed from 1971 to 2012. Located to the east of James Bay, Baie-James covered of land, making it the largest incorporated municipality in Canada — only eight Unorganized area (Canada), unorganized territories were larger. Its territory almost entirely (about 98%) covered the administrative region of Jamésie, although it contained less than five percent of the population. Essentially, it was the remainder of the Jamésie Territory's land after all of the major population centres were removed. On July 24, 2012, the Quebec government signed an accord with the Cree that would result in the abolition of Baie-James and the creation of a regional government known as Eeyou Istchee James Bay Territory. The hydroelectric power plants of the James Bay Project, La Grande Complex were all located within the municipal boundaries of Baie-James, making the municipality s ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ...

Landforms Of Nord-du-Québec
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...
