Palouse the Tuscany of America (9 pictures)
A major agricultural area of USA, Palouse encompasses parts of southeastern Washington, north central Idaho and, in some definitions, extending south into northeast Oregon. It is a truly spectacular sight.
Researchers believe that the dunes were formed during the Ice Age. Today this highly fertile area of USA supplies a large portion of the continent with vegetables and wheat.
Palouse is situated about 260km (160mi) North of the Oregon Trail.
