The Manicouagan River is a river in Côte-Nord region of Quebec, Canada. The river originates in the Manicouagan Reservoir and flows approximately 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 diameter asteroid which excavated a crater originally about wide, although erosion and deposition of sediments have since reduced the visible diameter to about . The Manicouagan crater is the sixth-largest confirmed impact crater known on earth.〔(Earth Impact Database )〕 The river's name, often abbreviated to Manic, is believed to come from a Montagnais word meaning "where tree bark is found". However the Innu of Betsiamites call it ''Menukuanistuk Shipu'', which means "river of the cup". ==Tributaries== The major tributaries of the Manicouagan River are in upstream order: * Toulnustouc River * * Isoukustouc River * * Fontmarais River * Lemay River * Manicouagan Reservoir * * Mouchalagane River * * Seignelay River * * Themines River 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Manicouagan River」の詳細全文を読む スポンサード リンク
