The Palouse is the most serene and pastoral of the seven wonders of Washington State. It is a region in south eastern Washington characterized by gentle rolling hills covered with wheat fields. The hills were formed over tens of thousands of years from wind blown dust and silt, called "loess", from dry regions to the south west. They look like giant sand dunes because they were formed in much the same way. In the spring they are lush shades of green when the wheat and barley are young, and in the summer they are dry shades of brown when the crops are ready for harvest. The Palouse hills are not only a landscape unique in the world, but they are beautiful to behold.
