Mississippi River Basin
Sieur de La Salle, a French explorer, found the Mississippi River in 1682 and claimed it and the waters draining into it for France. The Mississippi River, 2,348 miles long, is the longest river in the United States. It ranges in depth from nine feet to 100 feet, and its drainage basin includes over one million square miles. Idea: Trace a map of the United States. Color the states whose rivers empty into the Mississippi. Add tributaries, such as the Missouri, Ohio, and Arkansas Rivers.
