Just north of the Interpretive Center, this museum is housed in a 1932 Corps of Engineers survey boat. It covers the history of the Missouri River and has some unique L&C displays. Top, a diorama of Sgt Floyd's burial. Clark wrote an epitaph: "This man at all times gave us proof of his firmness and Determined resolution to doe Service to his Country and and honor to himself." The Floyd likeness displays the Corps' basic uniform and weapon.
