The Missouri River

The Missouri River is the longest River in North America with a length of 3767 km. It joins the Mississippi in St Louis to form the fourth-longest water system in the world. The name Missouri was coined by French explorers to simplify the original Algonquian (A family of Native American language) term 8emessourit which means 'people with canoes'.  The Native Americans called the river Pekitanoui which means 'Muddy Waters'

Missouri flows through 7 states before merging with Mississippi in St. Louis

Missouri is formed by the confluence of the Jefferson River and the Madison River at the Headwaters State Park near Three Forks. It is joined by the Gallatin River near Ling Rock Ferry Crossing

Jefferson River originates from the Confluence of many rivers. The first spring starts in the Centennial Mountains and forms a creek called Hell Roaring Creek near Bower's spring

From St. Louis Missouri becomes a part of Mississippi and finally joins the Gulf of Mexico
