Located in the Mojave National Preserve, the Kelso Dunes are the third highest in the United States rising to about 600 feet. Shifting sands on the steep side of the dunes create a unique rumbling sound that has given these mobile mounds the alias “the singing dunes.” The dunes are ringed by high mountain ranges, and the overall effect is one of a great, stark beauty. A red-tailed hawk soaring above may be the only reminder that this is Southern California, not Mars.
