A dry lake bed, called a playa: the ﬂattest of all natural surfaces.
Fine mud and silt, eroded from the surrounding mountain, compose the playa. Water washes across the playa, suspending the sediments in a shallow, temporary lake. The particles then settle evenly over the lake bottom, maintaining a level surface as the water evaporates.
Resembling an island in a frozen lake, “the Grandstand" is an outcrop of bedrock surrounded by a sea of sediment.
The playa is called the Racetrack because of its famous moving rocks.
