For several decades now, the mystery and the paranormal have surrounded everything related to the roving rocks found in Racetrack Beach, in the Death Valley National Park, in California. Now, thanks to the technology that we have and a very high dose of patience, scientists claim to have found the definitive answer that explains the strange movement of these stones and the marked trail they leave on the ground and have even shown a great video that shows. Do not lose detail of its interesting results.
Observation of the roving rocks
To decipher the mystery, a group of scientists led by Richard Norris, of the Scripps Institution of Oceanography, moved 15 rocks each equipped with a GPS to the Valley of Death, which would be responsible for recording the slightest change of position of the same. Each was monitored with the help of a high-resolution weather station and cameras that filmed each time lapse in a southeasterly direction.
Although scientists knew that this experiment could be very long (estimated up to 10 years of waiting), something happened a couple of years later, in the winter of 2013, which allowed to see how this phenomenon developed and allowed to explain it in its entirety earlier than expected, as published in PLOS ONE.
How do the rocks move from the Valley of Death?
Although the implication of water, ice and wind in the movement of rocks had already been theorized before, even by one of the authors of this study, until now it had not been possible to prove with certainty and with a scientific criterion in the where the phenomenon occurs concretely.
According to the observation, the authors affirm that in order for the strange movement to occur, a series of events that unusually coincide must coincide. First, the ground must be filled with water deep enough to form floating ice during the winter, but in turn, it must also be shallow, so that the rocks are exposed. During the night, with the fall of the temperatures, a very thin layer of smell is formed, between 3 and 6 mm, which momentarily catches the rocks.

When the day returns, the temperatures rise again and the thin icy layer begins to melt, break and forming plates that move easily by the wind, although this is very light: of just 5.4 m /.
So these, in turn, move the rocks very slowly, at speeds of just 2 to 5 meters per minute in the direction determined by the wind, as well as the water that flows under the ice. This belies previous hypotheses that a thick layer of ice and strong winds would be necessary to produce the sliding rocks.
During the two and a half months of the existence of stagnant water on the surface of the valley, the movement of more than 60 rocks was observed and recorded, some of which moved up to 224 meters away and left the well-known trail that has awakened the imagination of so many since its discovery in the decade of 1940, time in which the phenomenon has been debated and attributed to from rational geological and magnetic events to interventions of extraterrestrial beings.
