This important map shows a very early boundary for the proposed territory of Arizona, which was to be located in the southern portion of New Mexico Territory. It is very detailed along the route of the wagon road and locates springs, mail stations, forts, tanks, Indian villages, missions, and much topographical info. The route from El Paso travels through Las Cruces, Cooke's Spring, El Piloneillo (near the current AZ/NM border), Parke's Railroad Pass and north to the junction of the Salt, then northwest to Pima Villages (Phoenix). A fascinating and rarely seen map.
