These special dunes are one of the largest deposits in the Mojave National Preserve. The history of these 45 square miles started between 2-5 million years ago with the Mojave River carrying quartz and feldspar sediment as it traveled from west to east. Today it's a popular hiking spot even though the 600 feet of elevation can feel a lot more intense in 120-degree weather. Water is not available so make sure you are amply supplied before you start exploring!
