Sailing Stones

 

The mysterious moving  stones of the packed-mud desert of Death  Valley have been a center of scientific controversy  for decades. Rocks weighing up to hundreds of pounds have been known to move up  to hundreds of yards at a time. Some scientists have proposed that a combination  of strong winds and surface ice account for these movements. However, this  theory does not explain evidence of different rocks starting side by side and  moving at different rates and in disparate directions. Moreover, the physics  calculations do not fully support this theory as wind speeds of hundreds of  miles per hour would be needed to move some of the stones.
