Algodones Dunes

The Algodones Dunes are a vast, arid sand dune system located in southeastern California near the border with Arizona. Spanning over 40 miles long and up to 5 miles wide, this is the largest dune field in the United States. The dunes are characterized by steep, shifting slopes of fine sand, reaching heights up to 300 feet above the surrounding desert floor. The terrain is constantly reshaped by strong desert winds, creating a dynamic and dramatic landscape. The dunes are situated within the Sonoran Desert, surrounded by creosote bush scrubland and scattered dry washes.
