Lewis and Clark Trail Maps: a Cartographic Reconstruction, Volume II Martin Plamondon

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.

The maps contrast the modern riverbeds to their courses at the time of exploration. Also included are pertinent excerpts from the journals and depictions of significant geographical features.

Plamondon has utilized the actual traverse measurements and notes recorded by William Clark for each day that the expedition was on the move.
