The Sonoran Desert is the most biologically diverse of the four U.S. deserts. Covering 120,000 square miles of southwestern Arizona, southeastern California, and the Mexican states of Baja and Sonora, its mountains, rivers, and canyons provide luxurious habitat for numerous unique species specially adapted for heat, aridity, and intense summer monsoons.
