A stone that will "go" in America's Death Valley [Photos]

<

“Death Valley” is a 208 km long, 8-18 km wide mountain basin located in the eastern foothills of the Sierra Nevada in Arizona. Death Valley is the driest place in the United States, with an annual rainfall of less than 100 mm; it is also the hottest place in the United States with a maximum temperature of 56.6°C. The mystery of Death Valley also stems from the most distinctive stones.

The stones in Death Valley can crawl like animals. In 1969, the scientists carefully observed the stones in the valley and discovered that all the stones left their original position in the year, and they moved 364 meters away from the largest distance, leaving a long gap in the cracked ground.
