This is a great map of the western territories and the new state of California from this superb series of maps originated by Samuel A. Mitchell in 1846. Wheat states this map is a great step forward from Mitchell's previous edition, also published in 1850. This map carries the copyright notice of 1845 by H.N. Burroughs. Oregon Territory takes in all of present day Washington and Idaho. The huge and newly formed Utah Territory covers the region labeled Fremont Basin, and stretches from the California border to just past the Rocky Mountains. New Mexico Territory (also formed in 1850) encompasses parts of present-day Colorado and Arizona with its southern boundary on the Gila River in a pre-Gadsden Purchase configuration. The Gold Region is clearly marked along the Sacramento River and there is no county development shown in the new state. In the Pacific Northwest there is no sign of Portland, but Lima is shown across the river from Oregon City, Doctor Whitman's is shown upriver from Fort Walla Walla, and the Presb[yterian] mission is on the Koos Koos Kee River (Clearwater River) near its confluence with the Lapwai River. Another mission is further up the Clearwater River where the Canoe Camp of Lewis and Clark's route is marked.
