With appropriations from Congress, Secretary of War Jefferson Davis commissioned the Army Corps of Engineers to explore four routes from the Mississippi River to the Pacific Ocean. This map, published with their report, incorporated information from many previous expeditions. To aid Congress in selecting a route, it indicated locations of settlements, American Indian nations, and military posts.
