Manicouagan Reservoir (also Lake Manicouagan / m æ n ɪ k w ɑː ɡ ən,-ɡ ɒ̃ /; French: [manikwaɡɑ̃]) 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
It was reported that in the lead-up to the APEC forum in Sydney held in September 2007 certain key locations in images of the city's central business district, where APEC leaders were meeting, might have been intentionally reduced in resolution; however, Google has indicated that the change was unrelated to APEC, while the NSW police said that ...
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 table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 37 ] with the small but well-funded European continent having a large percentage of ...
