Its been a mystery for some time, but not anymore.
A team of knuckleheads got together and figured out how and why. "A rare combination of water and ice combines to move the rocks, the researchers said. The playa lake needs to be deep enough for floating ice, but shallow enough to leave the rocks exposed. The surface ice should be thin "windowpane" ice, but strong enough to break into big panels that can bully the rocks. Finally, the freezing nights need to be followed by sunny days with light winds, which drive the cracking ice across the lake."
Live Science has the full article and its pretty funny, some of the comments said. Enjoy it here.
The world is just a little less interesting.

Now we know how this stuff happens on Mars. maybe its not rivers or streams or roads but moving rocks
Hmm Very interesting. We know there are water crystals in the soil of mars. You could be on to something there.
