One of Johnson's first and most desirable issues of this map. It shows the United States when it had some of the most interesting territorial borders: newly created is Nevada from the western portion of Utah; Colorado from another portion of Utah and the upper portion of New Mexico Territory; Washington just gained the eastern portion of Oregon Territory, giving it an inverted "L" shape; and the proposed (or Confederate) territory of Arizona is shown in the southern part of New Mexico. Depicts railroads, completed and proposed, the Pony Express Route, and the U.S. Mail routes. Also shows the locations of the major Indian tribes.
