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 .
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.
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 ...
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 ...
There are situations where the censorship of certain sites was subsequently removed. For example, when Google Maps and Google Earth were launched, images of the White House and United States Capitol were blurred out; however, these sites are now uncensored. [3]
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 projectile was probably a stony asteroid, at least 2 kilometres (1.2 mi) in diameter, and weighing an estimated 15 billion tonnes (17 billion short tons). The Mont des Éboulements, situated in the exact centre of the impact structure, is interpreted as the central uplift, a consequence of elastic rebound. [3]
Geologists reached consensus by about 1970 that the Sudbury basin was formed by a meteorite impact. [citation needed] In 2014, analysis of the concentration and distribution of siderophile elements as well as the size of the area where the impact melted the rock indicated that a comet rather than an asteroid most likely caused the crater.
