Kelso Dunes is the largest field of eolian sand deposits in the Mojave Desert, covering 45 square miles. The tallest dunes rise up to 650 feet above the surround terrain. The region is protected by the Mojave National Preserve and is located near the town of Baker, California.The Kelso Dunes are also notable for the phenomenon known as singing sand, or "booming dunes." Enthusiasts typically climb to the top of the dunes and slide down slowly, generating a low-frequency rumble that can be both felt and heard. This effect has also been noted at the Eureka Dunes in California, Sand Mountain in Nevada, and the Booming Dunes in the Namib Desert, Africa.See you soon, sand.MP3: Linda Perhacs - Sandy Toes
