teacher Racetrack Playa Sailing Stones
Just a whisper of wind on a thin sheet of ice, and the heavy stones start to slide!
teacher The tracks left by the stones can stretch for hundreds of meters, showing straight lines, sharp turns, and parallel paths.
Playa flat surface: Racetrack Playa is so incredibly flat that its northern end is only about 4 centimeters higher than its southern end.
teacher The sailing stones are mostly dolomite and syenite rocks that break off from nearby cliffs and weigh up to 320 kilograms.
A flat-bottomed desert basin that temporarily fills with water before evaporating to leave a dry mud crust. In 2014, scientists discovered that thin, wind-driven ice sheets push the heavy rocks across this dry lakebed.
