A nice hand colored map of the US in the mid 19th century that shows the situation of the western territories, with one unique notation which is the notation for the territory of Mesilla cut from the southern portion of the New Mexico territory. Covering the southern border in what was the recent Gadsden purchase, the territory spans from the Gila River to the Mexican border, from Texas to the Gulf of California. The map does note numerous native tribes, as well as the location of "herds of Buffaloes and Wild Horses", as well as "Great American Desert".
