    This is not explained by science yet

    http://en.wikipedia.org/wiki/Sailing_stones

    The sailing stones (sliding rocks, moving rocks) are a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been recorded and studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not understood and is the subject of research.


    Racetrack stones only move every two or three years and most tracks develop over three or four years. Stones with rough bottoms leave straight striated tracks while those with smooth bottoms wander. Stones sometimes turn over, exposing another edge to the ground and leaving a different track in the stone's wake.


    Sliding rock trails fluctuate in direction and length. Some rocks which start next to each other start out traveling parallel, but one may abruptly change direction to the left, right, or even back the direction it came from. Length also varies because two similarly sized and shaped rocks could travel uniformly, then one could burst ahead or stop dead in its track.


    Speed is an unknown variable. Since these stones are rarely transported and nobody has witnessed the movement, the speeds at which the rocks travel are not known.

    That's a pretty weird phenomenon. The pictures are awesome. The rocks... They're alive!

    someone, perhaps, should take a month or two off work during the winter and park their RV next to a rock. watch it.

    Good idea earthpigg. Imagine watching a rock for two months straight, you could see it sprout legs and start running around and you wouldn't know whether or not you were crazy.

    Why hasn't someone just left a camera running for days, months, years, etc to check this stuff out?

    They probably have. They just haven't figure out how it works. It's not like the rock moves a massive distance in one go (does it?) it probably happens over a fairly long period of time.

    It probably moves pretty fast when they speed up the video...

    It's probably just tectonic, or magnetic.

    Very interesting. One would need to take a closer look at the tracks but as the scientists don't think that the wind alone is enough to move the larger rocks perhaps the physics are something to do with the fulcrum based mechanics used by the man in the video linked below.

    http://sciencestage.com/v/951/building-stonehenge.html

    In an environment of such temperature variation with the heavy rocks and a compressible surface as compressed dry mud can hold more water than uncompressed dry mud when the ice freezes, and expands, there is a good chance it will do so mostly where the pressure of the rock is least.


    Looking closely at one of the hd photos from wikipedia the edges of the track do seem jagged which is what one would expect if the larger rocks were “walking” on their fulcrums in response to the wind.
