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. A rain of about 1/2 inch, will wet the surface of the playa, providing a firm but extremely slippery surface. Strong winds of 50 mph or more, may skid the large boulders along the slick mud.
How was the Racetrack Playa formed?
During periods of heavy rain, water washes down from the surrounding mountains draining into the playa, forming a shallow, short-lived endorheic lake. Under the hot desert sun, the thin veneer of water quickly evaporates leaving behind a surface layer of soft slick mud.

Why is Death Valley so hot?
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. On sunny days, melting caused the ice to break into large floating panels that, driven by light winds, pushed against the rocks to move them, leaving tracks on the desert floor.
