The Sonoran Desert is located in the southwest region of Northern America. It covers an area of approximately 100,000 square miles, spanning southeastern California and southwestern Arizona in the United States of America, and most of Baja California and western Sonora in Mexico.
The Sonoron Desert, including the Colorado and Yuma desert subdivions, is one of North America's hottest and wettest deserts, resulting in high levels of biodiversity in the region. The desert is home to such animals as coyotes, antelope, mountain lions, wolves and owls, alongside various types of cacti and desert plants. Because of the region's unique climate, it is home to several species found nowhere else in the world, including the saguaro cactus.
