Lewis and Clark Visitor Center
The Lewis and Clark Visitor Center features exhibits about the history of the Missouri River basin, covering its geology, exploration by Lewis and Clark, early navigation, settlement, natural history, and the Gavin Point Dam. There are wayside exhibits (interpretive panels) located outside the center that provide more information about the Lewis and Clark Expedition. The center's theater shows films about the expedition as well as other topics such as the dam.
Backstory and Context
The Sioux informed to Lewis and Clark that they were living in a precarious state, with many women and children living in poverty, and wanted to open trade relations with the United States. They had already been in contact with French and British traders. The Sioux also wanted ammunition and rifles (and possibly whiskey). Lewis and Clark did not provide them with these but did offer them an invitation to Washington D.C. to being trade negotiations, which they accepted.
