Moving Stones of Death Valley, California
The valley was named Death Valley, because in the early years of the 19th century, people who came to America to search for gold mines had to cross the valley. Due to its high temperature and drought, many people were killed during crossing the valley. Due to these terrible conditions the valley was named Death Valley. When the Valley was studied in the year 1870, many skeletons of animals and humans were found here. In 1933 this valley was declared the National Monument of America. Every year 4 to 5 lakh people visit here to see its strangeness. But more bizarre and shocking thing than this is the sliding stones of this valley. These stones are also known as Sailing Stones. In the area of this valley, stones up to 320 kg have been seen changing their places. Sailing stones, also known as sliding rocks, rolling stones, and moving rocks, are a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention. Have you ever heard before that the stones are sliding away from their places without any help. How is it possible that due to being so weighty, these stones are still able to move from their place without any external force. But it is absolutely true. But scientists believe that it happens due to high speed winds. Other scientists believe that weather conditions are responsible for strange behavior of these stones. The research done on this explains that the 90-miles per hour wind speed, nightly frozen ice and thin layers of wet clay over the surface are responsible for moving the stones.
