The story of the Lewis and Clark expedition is one familiar to every American but many important figures in the story have gone unnoted.

Robert R. Archibald tells new pieces of the story through the lens of the Missouri Historical Society’s exhibit, Lewis and Clark: the National Bicentennial Exhibition.

Using vignettes, documents, and artifacts found throughout the exhibit, Archibald tells the story of the Native Americans Lewis and Clark interacted with along their westward journey.

He tells the story of Sheheke, a Mandan who provided maps and food for the explorers; Cameahwait, who gave Lewis an otter skin mantle that began his transition away from identifying with white American culture; and Sacagawea who served as the expedition’s intermediary between the tribes and white explorers.
