These rocks are famous because they move, leaving tell-tale trails in the clay, like this one. This happens at several playa in California and Nevada. There is no record of anybody seeing one of the rocks move and scientists aren't quite sure how it happens. But they know that it's not the work of animals, gravity, or earthquakes.
Fly Geyser: The Fly Geyser, near Gerlach, Nevada, is strange because it somehow grows up. It is three meters high at the moment. It is interesting that this geyser is located on private area, so nobody can enjoy it from close. The owner is Bill Spoo, a man who rejects the opportunity to make a fortune from the tourists, and keeps the beautiful view just for himself and the few researchers and photographers who have to schedule a visit weeks before arriving.
