Stones of Death Valley

Geologists American Space Agency (NASA) say that have solved one of the greatest mysteries of nature - the phenomenon of "moving stones" located in Death Valley (USA) on the bottom of the dry lake Reystrek Playa.

The question of how the huge boulders, some the weight of which exceeds 300 kg, moved by themselves, stirred the minds of scientists for nearly a century, giving rise to many myths and theories of the supernatural, but still remained zagadkoy.Primechatelno that the very movement of the stones still then no one could see. However, that really move boulders, eloquent traces left on the sandy bottom ozera.

Professor Ralph Lorenz of the Johns Hopkins University in 2006 conducted research for NASA in Death Valley. He believes that the secret of "moving stones" in that they are covered with ice in the winter, and during the thaw - glide on the surface due to por.

Scientist developed his theory on the basis of a simple experiment, which he spent at home. He froze in the water a small stone so that some part of it remained above the water. Then he turned it over and put it in a small swimming pool with a small amount of water and sand at the bottom, thus reproducing the conditions that occur at the bottom of the lake during the thaw. Ice stone quite easily allowed to "float" on the surface of the pool in a makeshift "dirt." At the same time to the stone began to move, it was quite small dunoveniya.
