The famous Death Valley in California, USA, is one of those places with the lunar aspect, where life would seem impossible. Feared and avoided by natives until the arrival of European settlers, arid valleys of California system and was named in 1849. It seems that when a group of gold diggers in tempting to reach gold mines in Sacramento, to ventured into dreaded crossing valleys.
Although apparently easier than crossing the mountains, the road would soon prove a nightmare for those intrepid few. Having lost in the endless desert, gold seekers wandered for 26 days until they were rescued by one of the spies sent to find a way out. It is said that when the passengers have left the valley, one of them has returned to the front once desolate wilderness uttering these words: '' Goodbye, Death Valley! ''. Thus name appeared bleak valley.
Aliens ? A supernatural force that people can not see ? A strange wind that stirs unimaginable forces ? Which is why the massive rocks of Death Valley, California, moving without being touched by human hands? Although experts have tried to find an explanation for this phenomenon, the mystery is not fully elucidated.
Death Valley National Park in the US state of California is where to spend an inexplicable phenomenon. Basically, in the area called Racetrack Playa rocks several sizes large enough to be slow and long leaves traces on the ground in the valley smooth, without human or animal. The phenomenon is all the more surprising as some moving stones weighing about 300 kilograms.
Rocks have traces of movement between meters and tens of meters, a width between 10 and 30 centimeters and a depth of 2 centimeters. They move only every two or three years, and most traces are made in three or four years. Whose base are rough stones left behind rectilinear grooves striated, smooth stones while changes direction, going often zigzag.
Obviously, such a mystery was never going to leave them, indifferent scientists. Researchers and lovers of curiosities studying rocks poignant since 1915 when it was first published a scientific paper on this phenomenon. The theory advanced in this paper was that the stones are set in motion some small tornadoes that formed after the arid land of Death Valley is reached by rain.
Another theory is that the stones moving moves as a result of a magnetic phenomenon unknown. However, the idea has been slightly inconsistent after it has been found that the stones do not contain significant amounts of elements with magnetic properties such as iron. Moreover, if the theory of magnetic phenomena were valid rocks supposed to gather in one place, which is not the case. Obviously, such a mystery was never going to leave them, indifferent scientists.

Yet, Death Valley has not always been worthy of the sad reputation that surrounds it. Archaeological discoveries have shown that if millions of years ago, represent the bottom of a big huge place, with only 10,000 years ago, the valley was a true oasis, full of lakes, the perfect environment for the continent's first inhabitants of North American.
The last hypothesis, the scientist issued by Paula Messina, and seems most plausible. A geologist claims the move stones as the result of several different factors. Using images obtained from satellite Messina sees a connection between the rainy and the strange journey of rocks. According to his theory, the clay from the mountains is carried by streams of water, covering the valley like a slippery mass. In such an environment, winds exceeding 100km / h can easily push the stone and prints them at speeds up to 2 meters / second.
And yet, there is no generally accepted explanation. In 1994, Death Valley was declared a national park, prohibiting its director's scientists to monitor the stones moving through radio transmitters.
However, although such an explanation is plausible, it is quite difficult to prove because nobody could see or record the movement of these rocks moving. And until someone does, the phenomenon remains a mystery.
