While this map presents most western boundaries as settled, it does show an early depiction of Wyoming, which is labeled in outline text only (it became a territory in 1868). Here Wyoming's northwest boundary juts out into Idaho, while Idaho in turn extend into parts of present-day southwestern Wyoming including Jackson Hole and the Grand Tetons. In the Southwest, Arizona includes the southern tip of Nevada. The track of the Pony Express, Fremont's route of 1844, the routes of the proposed transcontinental railroads, and locations of army forts are depicted. Surrounded by a decorative border. This is version 2.0 in the Johnson Map Project, which considers this map edition rare. Published in 1866.
