The Missouri is the longest river in North America, rising in the Rocky Mountains and flowing east and south for 2,341 miles – 3,767 km – before connecting with the Mississippi north of St. Louis.
History for over 12 thousand years, people have depended on the Missouri River as a source of food and transportation as ten Native American groups have led nomadic lifestyles along with the buffalo herds. In the late 17th century, Spanish and French explorers reached the river which become part of the United States with the Louisiana Purchase of the early 1800s.
