Mysterious Sailing Stones moving sailboat packed mud in the desert in Death Valley is a center of scientific controversy for decades.
Rocks up to several hundreds of pounds have been known to travel up to several hundred meters at a time.
Some scientists have proposed that the combination of strong winds and the ice surface into account these movements.
However, this theory does not explain the evidence of different types of rocks from side to side and moves at different speeds and in different directions.
Furthermore, the calculations of physics do not fully support this theory, because the wind speed is hundreds of miles an hour may be necessary to transfer some of the Sailing Stones.
