The Mississippi river's source begins at the Source of Red Rock, Montana and ends in the Gulf of Mexico.The Mississippi River is the largest river system in North America.About 3,710 miles long, the river originates at Lake Itasca, Minnesota and flows slowly southwards in sweeping meanders, terminating 95 river miles below New Orleans, Louisiana.The current form of the Mississippi River basin was largely shaped by the Cordilleran Ice Sheet of the most recent Ice Age. The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin.
