A sailing stone from Racetrack Playa


Geology.com has multiple photos and some discussion of the sliding rocks at the playa in Death Valley.   I like this one from Fresh Photons because it shows a right-angle turn.  GPS-generated maps of the movements are posted here, and there are more pix here.

Addendum 2013:  A hat tip to reader Bobbie who alerted me to a Smithsonian article offering a possible explanation of the stones' movements.
