Desert Arizona is a region in the southwestern United States that includes the state of Arizona. It is characterized by its hot, dry climate and sparse vegetation. The term Desert Arizona can refer to the entire region or to specific features within it, such as the Mesa, Mesas, and ADOBE. The Mesa is a flat-topped mountain or hill with steep sides, while Mesas are similar but smaller. ADOBE is a type of building material made from sun-dried mud bricks. All three of these features are common in the Desert Arizona region.
