This rare map of the Southwestern United States and Mexico shows the border along the Gila River prior to the Gadsden Purchase, a transaction that occurred the same year as the map was published. The new state of Texas is well-detailed, and California is named as New California. The New Mexico Territory includes what would become Arizona and portions of present-day Nevada. Indian Territory stretches into the region that became Colorado, and Utah Territory sweeps all the way to California. Surrounded by a keyboard style border.
