Ancient Travel Routes


The Mississippi River begins at Lake Itasca in Minnesota and flows 2,350 miles to the Gulf of Mexico near Venice, Louisiana. The area drained by the Mississippi watershed covers about 40% of the lower 48 states, and about 40% of the nation's migratory waterfowl use the river basin as a migratory flyway.
