Map of an Exploring Expedition to the Rocky Mountains . . . and to Oregon and North California . . . , hand-colored map by Brevet Capt. J.C. Frémont, 1845

John C. Frémont led five scientific expeditions into the West between 1842 and 1854; three of them were for the Army Corps of Engineers. This map, based on two expeditions, accompanied a report to the U.S. Senate. It accurately depicted large areas of the West, including locations of American Indian nations, but left blank the places unexplored by Frémont’s expeditions.
