In one of the HOTTEST places in the world, there is a seasonally dry lake bed that is home to what we call sailing stones. In this lake bed there are hundreds of rocks that seem to move completely on their own. Now by move I don't mean walk around like a person I mean they move nanometer by nanometer. The only reason we know they move is by the trails that they leave behind. The lake bed that they occupy has been aptly named "the racetrack".
The mysterious stones slide on very smooth ground. Some scientists think that the stones move through the lake bed when the mud is wet with help from the wind and ice crystals that build up on the rocks on cold desert nights. This theory is often shot down because the stones move in the summer when the lake is dry and the temperatures are FAR above freezing.
What is more interesting is that every stone takes it's own path as is if they have minds of their own.
