Manicouagan Reservoir (also Lake Manicouagan / m æ n ɪ k w ɑː ɡ ən,-ɡ ɒ̃ /) is an annular lake in central Quebec, Canada, covering an area of 1,942 km 2 (750 sq mi). The lake island in its centre is known as René-Levasseur Island , and its highest point is Mount Babel .
A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec. It may be an ancient asteroid impact crater. A Camper Was Playing With Google Maps—and ...
One of the largest impact crater lakes is Lake Manicouagan in Canada; the crater is a multiple-ring structure about 100 km (60 mi) across, with its 70 km (40 mi) diameter inner ring its most prominent feature; it contains a 70 km (40 mi) diameter annular lake, surrounding an inner island plateau, René-Levasseur Island.
Mistastin crater was created 36 million years ago by a violent asteroid impact. [9] The presence of cubic zirconia around the crater rim suggests that the impact generated temperatures in excess of 2,370 °C (4,300 °F) — roughly 43% that of the surface of the Sun and the highest crustal temperatures known on Earth [9] — and produced global changes that lasted for decades after the impact.
With a total area of 2,020 km 2 (and a diameter of 50.7 km), the island is larger in area than the annular lake in which it is situated. René-Levasseur Island is the world's second-largest lake island (the largest is Manitoulin Island in Lake Huron). [1] The geological structure was formed by the impact of an asteroid 214 million
West Hawk Lake is an impact crater lake on the Whiteshell River located in the Whiteshell Provincial Park in southeastern Manitoba, Canada. The circular shape of the main body of the lake is due to the submerged West Hawk crater, caused by a meteor impact into an ancient rock bed composed of mostly granite. At 115 metres (377 ft), it is the ...
The Pingualuit Crater (French: Cratère des Pingualuit; from Inuit "pimple"), [2] formerly called the "Chubb Crater" and later the "New Quebec Crater" (French: Cratère du Nouveau-Québec), is a relatively young impact crater located on the Ungava Peninsula in the administrative region of Nord-du-Québec, in Quebec, Canada.
The origin of the Nastapoka arc has been a source of disagreement and discussion among geologists, other Earth scientists, and planetary geologists.Noting the paucity of impact structures on Earth in relation to the Moon and Mars and remarkable curvature of the shoreline of this part of Hudson Bay, Beals [1] proposes that the Nastapoka arc is possibly part of a Precambrian extraterrestrial ...
