Manicouagan River

Surveying the Manicouagan River at the first falls, 1919

The Manicouagan River is a river in Côte-Nord region of Quebec, Canada. The river originates in the Manicouagan Reservoir and flows approximately 200 kilometres (120 mi) south, emptying into the Saint Lawrence River near Baie-Comeau. The reservoir, also known as Lake Manicouagan, lies within the remnant of an ancient eroded impact crater (astrobleme). It was formed following the impact of a 5 kilometres (3.1 mi) diameter asteroid 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). The Manicouagan crater is the sixth-largest confirmed impact crater known on earth.
