US archaeologist Colby examines the life and adventures of the son of the famous guide to the Lewis and Clark expedition and a French fur trader. She says that Charbonneau (1805-1866) integrated the voyageur lifestyle of his father's people, the Native American heritage of his mother's people, and the Jeffersonian tradition of his guardian William Clark.
