Lewis & Clark State Historic Site is site #1 on the Lewis & Clark National Historic Trail. The Corps of Discovery, led by Meriwether Lewis and William Clark, followed the Missouri River and crossed the Rockies, reaching the Pacific Ocean in late 1805. The interpretive center contains a 55-foot, full scale replica of the expedition’s keelboat, exhibits describing the journey, and outside, a replica of Camp River Dubois where the Corps of Discovery spent five months preparing for the expedition.
