Salt and dry lakes
A playa is a lake that is usually a floor: salt, alkali, and a horizon with nothing on it.

Bonneville, the Alvord, and the Sun Tunnels sit on this list beside the desert chapter they already belong to. Black Rock Desert is the big Nevada flat. Racetrack Playa is the sailing-stone floor in Death Valley, on a rough high-clearance road. Salt Plains in Oklahoma grows selenite. Carrizo Plain holds Soda Lake on the San Andreas. Smoke Creek is the empty basin north of Pyramid Lake.
