Then the strong wind can move flat stones along the flat ground. The water on the ground changes to very thin ice. Rain falls, and the hard ground becomes soft and wet. Sometimes there are bad storms in the night. Death Valley is one of the hottest places in the world, but it can be very cold at night. But how can the wind move a stone that weighs 350 kilograms? When the wind is from the south, they always move to the north. When the wind comes from the west, the stones move to the east. Nobody has ever seen them moving, but now scientists know the answer to the question. The stones only move at night and only once every year or two. Some of the big stones are as big as a man.
Many of the stones are small but a few of them are very big. These famous moving stones are in Death Valley, USA. But how do they move? Scientists have tried to answer this question for the last 50 years. The long tracks show that the stones have moved along the ground. These big stones leave long tracks behind them.
