The desert located directly south of the Mojave Desert is the Sonoran Desert.

The Sonoran Desert is located just south of the Mojave Desert, covering parts of southwestern Arizona, southeastern California, and northern Mexico. Unlike the Mojave, the Sonoran Desert receives more rainfall, making it a more biologically diverse region. The Sonoran Desert is famous for its iconic saguaro cactus and a wide variety of plant and animal species, some of which are unique to this desert. Its ecosystems range from dry, arid areas to more lush, semi-arid regions. The Sonoran Desert's diverse landscapes and rich biodiversity make it an important ecological area in North America.
