'Death Valley' in America

The most difficult thing to explain in " Death Valley " is the traces of free movement of stones.

>>> Mysterious stone moves itself on Death Valley

In the 'Death Valley' almost all year round there is not a rain drop and there are up to 6 weeks in a year the temperature reaches over 40 degrees Celsius. Whenever there is rain, the hot places will have red mud layers that appear to look like volcanic eruptions. Therefore, this place is also called ' dead crater '.

The name ' Death Valley ' was used 150 years ago. In the winter of 1849, a group looking for gold passed through this valley. Because they were unable to cope with the harsh weather here, they were just white piles of bones buried in immense sandy sea. A small number of people, after coming out of this place, shouted that 'goodbye to the death valley' and the name 'Death Valley' was born from there.

However, the most difficult thing to explain in " Death Valley " is the traces of free movement of stones. NASA scientist Brian Jackson said that this mystery makes people associate this place with another planet.

For more than a month, these rocks move about 100 meters. No one can explain why these stones can be moved.

After heavy storms, water often focuses on the surface of these strange stones. However, that is not enough to explain their mysterious movement. The paths of these stones do not follow any rules.

A few weeks ago, an expedition consisting of 17 scientists and students under the guidance of NASA staff came here to study.

How long the rain has not stopped, the ground has quickly dried and cracked.

The stones scattered in the desert are normal rocks, but nothing special because they are all falling from the mountains.

Researchers GPS satellite systems to study the trajectory of rocks. In addition, they also analyzed the soil in this area. After ten years of research, scientists still did not get any results. They have to make new assumptions.

Last winter, a NASA employee put the sensor down on a hole beneath the rocks. The results showed that there was a freezing phenomenon in March.

And whether the ice sheets that move the stones is still a big question.
