These observations contradicted earlier hypotheses of strong winds or thick ice floating rocks off the surface. It was postulated that small rafts of ice form around the rocks and the rocks are buoyantly floated off the soft bed, thus reducing the reaction and friction forces at the bed. The National Park Foundation is a 501(c)3 non-profit organization. Instead, they proposed that during winter storms in the region, wind flow created water currents of around two meters per second which stirred up the soil around the rocks in the region, creating grooves. A slight wind is enough to move the ice platform and rock, which slide on the slippery mud bottom. As it freezes, it rises to the surface, creating a paper-thin sheet of ice beneath the rocks.

A steady wind drag moved the thin ice sheets covering the playas south end, and these sheets pushed the rocks along, creating the characteristic furrows in the playas muddy surface. These thin floating ice panels,[17] frozen during cold winter nights, are driven by light winds and shove rocks at up to 5 m/min (0.3km/h; 0.2 mph). The movement of the rocks occurs when large, thin sheets of ice floating on an ephemeral winter pond break up in the sun. But it still fascinates us how inventive nature can be.

However, there are some other places in the world where a similar mechanism takes place. Picture Wiki The dry lake of Racetrack Playa in California's Death Valley is famous for them. Researchers documented multiple rock movement and trail formation events by in situ observation, video, time lapse cameras, a dedicated meteorological station, and GPS tracking of instrumented rocks. The researchers also observed rock-less trails formed by grounding ice panels features that the Park Service had previously suspected were the result of tourists stealing rocks. The largest stone to move was 80lb (36kg). The tracks the stones leave can go on for several hundred feet. They only stop when the water dries, or when the water freezes again.
