The region of southeastern Washington and adjacent Idaho that has rolling hills on deep soils is known as the Palouse. On its eastern border, this region is bounded by the forests of northern Idaho, and the Snake River forms its southern boundary. To the north and west, the Palouse is bounded by areas of flat terrain and shallow soils, places where the deep soils were scoured away by ice or water during past glaciations or floods.

The peculiar and picturesque silt dunes which characterize the Palouse Prairie were formed during the ice ages. Blown in from the glacial outwash plains to the west and south, the Palouse hills consist of more or less random humps and hollows.. The steepest slopes, which may reach 50% slope, face the northeast. Large areas of level land are rare.
