Sonoran Desert Silloutte

Next to the 10-gallon hat and the cowboy boot, there is no more widely recognized symbol of the Southwest than the giant saguaro cactus. (pronounced "suh-wahr-oh"). And nowhere else in the region can you find more of these famous figures than Saguaro National Park, in the Sonoran Desert just outside of Tucson, Arizona. 

Saguaro National Park covers about 150 square miles of mountains and desert scrub. It's a wildlife corridor for species like Gila monsters, javelinas
 (distant relatives of a wild pig), and desert tortoise.
