In Volume II, Martin Plamondon continues his cartographic reconstruction of the Corps of Discovery's trek across the northwestern United States in 1805-6. Beginning a short distance above Fort Mandan, 180 full-page maps depict the explorers' route on the Missouri River in western North Dakota and Montana, over the continental divide to Idaho, and down westward-flowing waters to the Snake-Columbia confluence in central Washington.
