Manicouagan crater

Manicouagan crater is an impact structure in Quebec formed by an ancient meteorite strike, now filled with a large reservoir. A circular island named René-Levasseur rises from the water at the center of this geological formation.

The structure formed roughly 214 million years ago when a meteorite struck Earth during the Late Triassic period. This ancient impact left one of North America's best-preserved crater formations.

Indigenous communities near the crater maintain oral traditions connecting the geological formation to their understanding of the natural world.

The best viewpoint is from Highway 389 along the eastern shore of the Manicouagan Reservoir. Multiple spots along this road offer views of the circular formation from different angles.

René-Levasseur Island holds the Louis-Babel Ecological Reserve with Mount Babel rising about 950 meters above the reservoir. This central island serves as an important habitat for wildlife in the region.
