"Our wonderful Palouse region is the most serene and pastoral of the seven wonders of Washington State. It is a region in southeastern 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 (and pronouned luss) from dry regions to the southwest. Seen from the summit of 3612-foot high Steptoe Butte they look like giant sand dunes because they were formed in much the same way. The Palouse hills are not only a landscape unique in the world but they are beautiful to behold and worthy to be on the list of Seven Wonders of Washington State."
This was an excerpt from Howard Fisk's book, The Seven Wonders of Washington State: Your guide to exploring the natural wonders of the Evergreen State, published in 2015 and available via Amazon.
Green in the spring, golden brown at harvest time and snowy white in winter.... Washington's Palouse is a beautiful and very unique region.
