Sand Mountain in Nevada is known for it's booming sand. If you can find a spot that's relatively undisturbed, and create a small avalanche (say, by riding down it with your brakes on) the sand will vibrate at a low frequency, sounding much like a WW2 bomber in flight.

Anybody else notice this at their local sandbox? I don't know if ALL sand does it, or only a few?

That's really interesting. At first I thought it was a recording of a humpback whale or something:D I've never heard that where I ride. But then again, I can't really hear much over the rumble of my X6.:confused:

Killpecker Sand DUnes near Rock Springs, WY do that too. I've heard it before. You need to get the sand moving like Wilkin250r said - I did it by hitting the front brakes going down a dune.

It's imperitive that the sand be absolutely dry (which isn't a problem in Nevada) so if it rained recently, you won't be able to hear it.
