What causes the moving rocks of Racetrack Playa?

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

The biggest factor behind Death Valley’s extreme heat is its elevation. That really allows for the solar radiation to heat up the air, and really dry it out. The valley is narrow, trapping any air from circulating in or out. There’s also little vegetation to absorb the sun’s rays, and there’s a desert nearby.

What makes the rocks move in Death Valley?

There had to be a shallow layer of water in the dry lake bed and nighttime temperatures cold enough for the formation of a thin layer of ice.
