Stupid theory! Sliding rocks of Death Valley

                          Hi! Today I'll be talking about the sliding rocks of Death Valley.


A bizarre event that is puzzling the science world - rocks that glide across the desert.

Weird rocks of  the valley

 Amid the eerie silence and the 50C heat of California's Death Valley these giant boulders appear to move smoothly - and unaided - across the desert.The rocks, some as heavy as 17 stone, edge along in bizarre, straight-line patterns across the surface of the valley. They can travel more than 350 yards a year. 


I have the answers. 
1)Since nobody can probably go there, and nobody has lifted the rocks, there're probably millions of millions of microorganisms under rocks moving them .

An abnormal rock

                           

2)Even though it's hot down there, there's still wind and snow. So, when the snow melts, the wind will probably freeze it over the valley. so, Since the valley is not flat/straight, the rocks will slide!
