Here, the Missouri, Mississippi and Illinois Rivers meet to form a 35,000-acre floodplain. The Mississippi, a working river, is also an environmental treasure. Historic 18th-century river towns, islands, bars, points, and bends create beautiful scenery beneath limestone bluffs that are covered by forests extending over nearly 20,000 acres.
