How do the sliding rocks in Death Valley movie?

A research project has suggested that a rare combination of rain and wind conditions enable the rocks to move.

How do the sailing stones of Death Valley move?

They discovered that the rocks were nudged into motion by melting panels of thin floating ice, driven by light winds, in winter. The sailing stones, or sliding stones, of Racetrack Playa have been observed and studied since the early 1900s.

How fast do the sailing stones move?

The movement of the rocks occurs when large sheets of ice a few millimeters thick and floating in an ephemeral winter pond break up on sunny days. Frozen during cold winter nights, these thin, floating ice panels are driven by wind and shove rocks at speeds up to 5 meters per minute.

Do rocks move in Death Valley?

Who discovered the sailing stones?

But if they’re not magic, what really does cause the stones to sail? In 1948, two USGS geologists named Jim McAllister and Allen Agnew set out to answer the question. They proposed that dust devils caused the strange movement, perhaps in combination with the playa’s intermittent flooding.
