Whats up with those rocks that move across the desert floor in death valley ,az.or somewher?

Question

i saw it years ago on a show..have they figured it out yet?/..wind?.moisture at night?..any ideas?/

Answer 1

Death Valley, CALIFORNIA.

It's probably from ice forming on a slick mud surface of Racetrack Playa and high winds blowing the rocks around during the winter.

Answer 2

Cold desert nights, water condenses and freezes, winds blow rocks around as they are on a thin film of ice which is slippery enough.
