Photographed by one of the Expedition 34 crew members onboard the International Space Station, the crater is located primarily in Manicouagan Regional County Municipality in the Côte-Nord region of Québec, Canada, about 300 kilometers (190 miles) north of the city of Baie-Comeau. Manicouagan is one of the oldest large astroblemes still visible on the surface. The crater is a multiple-ring structure about 100 kilometers (60 miles) across, with its 70 kilometer (40 mile) diameter inner ring its most prominent feature; it contains a 70 kilometer (40 mile) diameter annular lake, the Manicouagan Reservoir, surrounding an inner island plateau.
