Death Valley National Park

A geological phenomenon transported this rock and etched the tracks visible on the dried lake bed before you. For years, scientists were baffled by the force capable of moving it across the valley. Then, in 2014, two scientists captured a timelapse of the rocks in motion. They discovered that the rocks drift when thin ice panels, formed underneath them on cold winter nights, begin to melt under windy conditions. Numerous such stones and tracks are found in this part of Death Valley National Park, aptly named Racetrack Playa.
