The Sonoran Desert covers parts of Arizona and California.

The Sonoran Desert spans across southern Arizona and southeastern California in the U.S., extending into the Baja California Peninsula in Mexico. Known for its striking biodiversity, the desert includes iconic landscapes like the saguaro cactus forests of Arizona and the California deserts. In Arizona, major cities like Phoenix and Tucson are located within the desert, while California’s southeastern regions, such as the Imperial Valley, are also part of this unique ecosystem. The desert’s varied geography, from sand dunes to mountains, helps support diverse plant and animal life, making it one of the most ecologically rich deserts in North America.
