One of our favorite places in the world lies across the USA/Mexico Borderlands, the Sonoran Desert.
The Sonoran Desert is the third largest North American desert and extends from the California-Nevada border south to the tip of Baja California and much of the state of Sonora. Two thirds of this desert lies in Mexico.
The surface is a mix of volanic and metamorphic rock. Northern Sonora’s Pinacate region is marked with craters and lava fields – volcanic activity is as recent as 1,300 years ago.
Among its unique and endemic plants are the saguaro (Carnegiea gigantea) and organ pipe cactus (Stenocereus thurberi).
