Sand Mountain is a dune over 100 meters high located just off U.S. 50 southeast of Fallon.
The map above shows clearly how the sand accumulates near a saddle as air flow funnels through the saddle, loses velocity, and drops its load.
|Unlike desert pavement, sand dunes tend to recover from damage pretty rapidly. So why not let folks play on one?|
