Scarce map of the Southwestern United States, published by the Society for Diffusion of Useful Knowledge.
The map shows a fine snapshot of the earliest Western Territorial Configurations following the admission of Utah and New Mexico as Territories.
The map is dominated by a massive Utah, New Mexico (pre-Gadsden Purchase), pre-dating Kansas, with a strange configuration for Nebraska.
While the earlier editions of this map include the Republic of Texas, this later pre-Gadsden edition rarely appears on the market.
Excellent detail and notations throughout the map, including notes on Indian Tribes, mountain elevations, topography, etc. A great collectors map.
