How does wind remove sediment from a dry playa surface?

On a dry playa surface, wind removes sediment primarily through a process known as deflation.

As the playa dries, the clay and salt deposits form crusts that naturally curl and flake. These loose flakes and curls are easily picked up by turbulent wind eddies. Once lifted, these fine-grained sediments—including silt and clay-sized particles—can be transported over long distances, often contributing to regional dust hazards.12

The sediment removed from the playa is typically deposited on the leeward side of the basin. This accumulation can lead to the formation of specific landforms, such as dunes or, in the case of clay-rich deposits, features known as lunettes. Over time, this continuous process of wind erosion can lower the surface of the playa, potentially creating deflation hollows or blowouts.12
