Pic Description: According to the British "Daily Mail" reported that a California Death Valley, scientists found, where some huge rock slowly sliding along the desert automatically, this strange phenomenon to scientists incredible. Death Valley these rocks on the heavy edge of the strange shape, and form a straight line through the ultra-flat valley. Scientists observed that they can move more than 350 yards a year (about 320 meters). U.S. scientists believe that the special local weather conditions led to the free movement of the rock. Wind speed at night in this region will reach 90 miles / hour and the temperature dropped rapidly in the region will make the desert bear wet clay surface layer of very thin ice. The combined effect of these two conditions can occur free movement of rock. Photographer Mike Benny (Mike Burne) for many years in the rock record of the mysterious movement. He took photos of those amazing, people see adults who have such a heavy boulder in the desert rolling marks. He said it is hard to imagine. Has a theory about the movement of rock, said, the wind beneath the surface of the backlog in the sand after the water onto to form a rock in the rolling surface. Death Valley 282 feet below sea level (about 86 meters), the lowest point of the United States. There is almost completely flat, where scientists have recorded the second highest in the Earth's surface temperature record of 58 degrees Celsius. 90 20th century, Massachu_set_ts (Massachu_set_ts) Hampshire College (Hampshire College) John Reid (Jone Reid), who led a group of people try to explain the phenomenon of rock movement. They concluded that the rocks embedded in sand at night ice formed on the surface, with the dissolution of soil, rock roll with the ice and wind to glide up.
