The Manicouagan cores
Its round shape and central island have earned Lake Manicouagan the nickname 'the Eye of Quebec'. This unique lake is located within a meteorite crater and is the deepest in Quebec, reaching depths below sea level. The lake is also part of the territory of the Innu people, which was lost in 1970 when the Manic-5 dam was commissioned. Léo Chassiot, a professor in the Department of Environmental Sciences at the Université du Québec à Trois-Rivières, has made it his mission to decipher the history of this now-submerged landscape, which is preserved in the lake's sediments.
