Eureka Flat: engine of the Palouse

Eureka Flat, shown in this DEM, is a deflational zone aligned with prevailing southwesterly winds. Percentage of sand within surface sediments of Eureka Flat document dunes that mantle the upwind surface, and show a fining downwind trend towards the loess-mantled landscape. The southwest portion of the flat has been a depocenter for glacial outburst flood sediment, a source for dust and eolian sand.
