Sand Mountain, Nevada
Quartz particles, which the glaciers had ground away from the hard Sierra granite to the west, eventually washed down the Walker River and deposited in the river's delta. As the wind blew across the delta this sand was picked up and carried high into the air. More than thirty miles to the northeast, the wind was slowed by a large basin on the southwest flank of the Stillwater Range. With its force broken by the mountain, the wind's burden of sand would fall into this natural trap.
Singing Sand Dune
Sand Mountain is a Singing Sand Dune, about 600 feet high, in a corner between two mountain ranges. When you slide down the mountain, it moans loudly. Singing Sand is very rare. It has to do with the shape of the grains of sand and the way they rub each other. Even on a windy day, if you are close enough you can hear it moaning.
