An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity 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.
Manicouagan Reservoir is an annular lake in central Quebec, Canada, covering an area of 1,942 km2 (750 sq mi). The lake island in its centre is known as René-Levasseur Island, and its highest point is Mount Babel. The structure was created 214 (±1) million years ago, in the Late Triassic, by the impact of a meteorite 5 km (3 mi) in diameter. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec". The lake has a volume of 137.9 km3 (33.1 cu mi).
La Moinerie is an impact crater in Quebec, Canada. It is 8 km in diameter and the age is estimated to be 400 ± 50 million years. The crater is exposed to the surface and filled with water, forming Lac La Moinerie. Glaciers have eroded many of La Moinerie crater's original physical features, including much of the central uplift. It is located in Rivière-Koksoak, in the Kativik territory.
Lappajärvi is a lake in Finland, in the municipalities of Lappajärvi, Alajärvi and Vimpeli. It is formed in a 23 km (14 mi) wide, partly eroded meteorite impact crater. The lake is part of Ähtävänjoki basin together with Lake Evijärvi that is located downstream (north) of it.
Marquez crater is a meteorite crater located in Leon County, Texas near the small town of Marquez about 177 km (110 mi) northeast of Austin, Texas, United States.
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).
The Pingualuit Crater, formerly called the "Chubb Crater" and later the "New Quebec Crater", is a relatively young impact crater located on the Ungava Peninsula in the administrative region of Nord-du-Québec, in Quebec, Canada. It is 3.44 km (2.14 mi) in diameter, and is estimated to be 1.4 ± 0.1 million years old (Pleistocene). The crater and the surrounding area are now part of Pingualuit National Park. The only species of fish in the crater lake is the Arctic char.
Saint Martin is an impact structure in Manitoba, Canada. It is located in the northern part of the Rural Municipality of Grahamdale, northwest of Lake St. Martin.
Lake Témiscouata is a lake in the Témiscouata region of southeastern Quebec, Canada. It is 40 km long, with a total area of 66 km2. The Madawaska River flows from this lake to the Saint John River.
Brûlé Lake is a lake in the Côte-Nord region of Quebec, Canada, the eastern shore of which marks the boundary with Labrador.
The Lac Wiyâshâkimî, also called the Clearwater Lakes in English and Allait Qasigialingat by the Inuit, are a pair of annular lakes and impact structures on the Canadian Shield in Quebec, Canada, near Hudson Bay.
The geology of Illinois includes extensive deposits of marine sedimentary rocks from the Palaeozoic, as well as relatively minor contributions from the Mesozoic and Cenozoic. Ice age glaciation left a wealth of glacial topographic features throughout the state.
The Grand lac Saint-François is a freshwater body covering 51-square-kilometre (20 sq mi), in the administrative region of Chaudière-Appalaches, in southeastern Quebec, in Canada. This water body is located in two regional county municipality:
Louis-Babel Ecological Reserve is an ecological reserve on René-Levasseur Island in Quebec, Canada. It is named after Canadian priest Louis Babel. It was established on January 30, 1991.
Lake Albanel is located east of Lake Mistassini and covers a total area of approximately 445 square kilometres (172 sq mi). It is located in the region of Jamésie. Quebec Route 167 ends beside this lake. It is entirely located in the protected area of Lacs-Albanel-Mistassini-et-Waconichi.
The Presqu'île Lake is a body of water forming a lake at 5.4 kilometres (3.4 mi) South of the center of the village Chapais, in the regional County Municipality (RCM) of Eeyou Istchee Baie-James, in the administrative region of Nord-du-Quebec, in Quebec, in Canada. This body of water straddles the townships of Lévy, de Brongniart, and Brochant.
Monturaqui is an impact crater in Chile. It lies south of the Salar de Atacama and was formed 663,000 ± 90,000 years ago by the impact of an IAB meteorite. It is 350 m × 370 m wide and 34 m (112 ft) deep and contains a salt pan. Only a few remnants of the meteorite that formed the crater have been collected, with most of the rocks being of local origin. The crater was discovered in 1962 and identified as an impact crater in 1966.
