What is Racetrack Playa famous for?
from cross-country races
from wandering stones
from strange lizards
from crying rocks
One of the most interesting mysteries of Death Valley National Park is the sliding rocks at Racetrack Playa (a playa is a dry lake bed). These rocks can be found on the floor of the playa with long trails behind them. Somehow these rocks slide across the playa, cutting a furrow in the sediment as they move. n 2013, scientists were able to directly observe the "stone journey" and discover in what conditions this phenomenon occurs.
