Where is the largest crater in Canada?

Manicouagan Crater – The Earth’s Largest Impact Crater Visible from Space. Manicouagan Crater, located in Canadian province of Québec, is one of the Earth’s oldest and the most visible impact craters. Manicouagan Crater was formed by an asteroid strike over 214 million years ago.

Is Lac Manicouagan a crater?

The crater is a multiple-ring structure about 100 kilometers (60 miles) across, with its 70 kilometer (40 mile) diameter inner ring as its most prominent feature; it contains a 70 kilometer (40 mile) diameter annular lake, the Manicouagan Reservoir, surrounding an inner island plateau, René-Levasseur Island.

Why is there a circle in Quebec?

The crater was formed following the impact of an asteroid with a diameter of 5 km (3 mi), which excavated a crater originally about 100 km (62 mi) wide, although erosion and deposition of sediments have since reduced the visible diameter to about 72 km (45 mi).

Why is René-Levasseur Island so round?

The impact of the meteorite formed a crater roughly 100 km in diameter, the centre of which forms the island known today. It became an artificial island when the Manicouagan reservoir was flooded in 1970, merging two crescent-shaped lakes: Mouchalagane Lake on the western side and Manicouagan Lake on the eastern side.
