George Drouillard was a member of the Lewis and Clark expedition. Born c. 1773, Drouillard was half Indian, spoke several Indian languages, and was familiar with Indian customs. The novel portrays him as a fearless adventurer, a great hunter, an excellent cartographer, and a superior boatman. On several occasions in the novel he provides nearly all of the game consumed by the expedition. Although he remains a minor character in the novel, he is mentioned more frequently than nearly any other member of the expedition. He never complains, is always at the forefront of the action, and on several occasions his heroic actions save others in the expedition.
