Daddy, why is the playa dusty?

This is what happens when you spend too much time on the interwebs–you find sites like this one. Ever wondered why the playa creates dust? Now you know everything.

Hydrology of Playas and the Genesis of Dust

The relations among playa type, playa hydrology, and surface sediment characteristics are important factors that control the type and amount of dust emitted from playas. The production of evaporite minerals during evaporative loss of near-surface ground water results in both the creation and maintenance of several centimeters or more of loose sediment at wet playas.
