Sand Mountain (Nevada)
Sand Mountain is a singing sand dune east of Fallon, Nevada along U.S. Route 50. The dune is two miles long and high.
The sand originates from the ancient Lake Lahontan, that for the most part dried up 9,000 years ago. Sand Mountain Recreation Area is managed by the Bureau of Land Management and is open to off-highway vehicle use. The area is also the only home of the "critically imperiled" Sand Mountain blue butterfly. The ruins of the Sand Springs Station of the Pony Express are also located within the recreation area.
