A map of ArizonaA map of ArizonaArizona is situated in the southwestern region of the United States. The Colorado Plateau makes up its northern part. Flowing across the plateau, the Colorado River has carved a long, deep gorge famous around the world as the Grand Canyon. It is 446 kilometres (277 miles) long, and ranges in width from 6 to 29 kilometres (4 to 18 miles) at a depth of more than 1.6 kilometres (1 mile). The river and its tributaries have cut through layer after layer of rock as the Colorado Plateau uplifted, exposing nearly two billion years of Earth's geological history. Also part of the Colorado Plateau is Monument Valley, a cluster of sandstone buttes (flat-topped “islands” of rock edged by near-vertical cliffs) on the Arizona–Utah border. Marking the southwestern edge of the Colorado Plateau is the Mogollon Rim, a 600-metre (2000-foot) escarpment, which cuts across the centre of the state. To the south is Basin and Range country, a series of mountain ranges interspersed with wide valleys. Much of this area is desert.

The name Arizona may have come from the Native American (O’odham) words ali sonak, meaning “small spring”, describing a small area around a silver mining camp in what later became part of Arizona. To the Europeans, the local pronunciation sounded like "Arissona". Another possible origin may be the Basque phrase haritz ona (“the good oak”) used by shepherds who originally came from the Basque area of northern Spain. Although the origin is uncertain, “Arizona” definitely did not originate from the Spanish term for “arid zone”, as some have thought. The Spanish for arid zone would be zona árida.


Arizona is one of the Four Corners states, a region of the US consisting of the southwestern corner of Colorado, the southeastern corner of Utah, the northeastern corner of Arizona and the northwestern corner of New Mexico. It is the only location in the US where four states meet at a single point.
