Phoenix is the capital of the state of Arizona as well as the most populous city in the American Southwest and sixth largest city in the United States . Founded in 1871, it has become the region's primary political, cultural, economic, and transportation center. At an elevation of 1100 ft (335 m), it is situated in the biologically unique Sonoran Desert. Over time it has merged with the neighboring cities of Scottsdale , Tempe , Glendale , Peoria , Mesa , Chandler , and Gilbert to form the Greater Phoenix Metropolitan Area . Currently exurbs such as Apache Junction , Fountain Hills , Queen Creek , and Sun City are becoming part of this metropolitan area as well. Phoenix is extremely hot in the summertime, so always have sun screen with you!
