Learn what species have survived since they were identified during the Lewis and Clark Expedition and how invasive species threaten the local ecosystem.

Displays cover pre-historic Indians; French explorers; riverboat traders; earthquakes; and Civil War battles. Located in the 1886 Kendal Saloon building. Adnission: $2.50; ages 6-12, $1.
