The rocks what moving alone.

I read about this rocks, and it is amazing how moving without any explication?

At places where this happen it is at Death Valley, in U.S.A, look like they are floating.

Everybody believe what this move is by the stroger wind, but this not is one explication for the rocks of different size and weights.

Also with their moves in parallel and way differents.

So the questions is if the wind can move small rocks...how move some of lot weight?
