Where is Arizona exactly? Well, it is in the Southwestern part of the U.S. with a 389 mile border with Mexico. In fact it was at one time a part of Mexico. It is one of the Four Corner states meaning that it borders Colorado, Utah and New Mexico at one point. You would think this might happen more often but this is the only place it does apparently. It also shares a border with California and a small portion of Nevada.
Most of the Four Corners region belongs to the semi-autonomous Native American nations, the largest of which is the Navajo Nation, followed by Hopi, Ute, and Zuni tribal reserves and nations.
