The second largest city is Tucson, followed in size by the eight Phoenix metropolitan area cities of Mesa, Glendale, Chandler, Scottsdale, Gilbert, Tempe, Peoria, Surprise and then by Yuma in Yuma County. Arizona is the 48th state and last of the contiguous states admitted to the Union, achieving statehood on February 14, 1912 - the 50th anniversary of Arizona's recognition as a territory of the Confederate States of America.[5] Arizona is noted for its desert climate, exceptionally hot summers, and mild winters, however it also features pine forests and mountain ranges in the northern high country, with cooler weather than in the lower deserts. Arizona is one of the Four Corners states. It borders New Mexico, Utah, Nevada, California, touches Colorado, and has a 389-mile (626 km) international border with the states of Sonora and Baja California in Mexico. It is the largest landlocked U.S. state by population. In addition to the Grand Canyon, many other national forests, parks, and monuments are located in the state, while more than a quarter[6] of its territory is Federal Trust Land which serves as the home of the Navajo Nation, the Hopi tribe, the Tohono O'odham and Apache people, various Yavapai tribes and others.
