Moving stones in Death Valley, California.
Previously, there was a dried-up pond, on which there were stones that could move. This is a natural task of nature so no one could photograph, but traces of the movement of stones still remain. The explanation was obvious. Water appears periodically at the bottom of the lake, at night in cold weather, ice forms there. When the ice melts during the day, the pebbles eventually move smoothly.
