The U.S. Southwest is known for its arid climate, and it includes the Sonoran Desert, which covers parts of Arizona and southeastern California.

The Southwest region of the United States, particularly Arizona and southeastern California, is known for its arid climate and is home to the Sonoran Desert. This desert region experiences extremely hot temperatures, limited rainfall, and vast stretches of rugged terrain. Unique plants like the saguaro cactus, as well as diverse wildlife adapted to dry conditions, thrive here. The Sonoran Desert has two distinct rainy seasons, which slightly differentiates it from other U.S. deserts, but overall, it remains a classic example of an arid landscape. Its dramatic scenery and harsh environment make the Sonoran Desert a notable feature of the U.S. Southwest.
