The Inland Northwest, also known as the Inland Empire, is a region in the Pacific Northwest centered on the Greater Spokane Area, that includes All of Eastern Washington and all of North Idaho. The region also contains the Tri-Cities. The portion of Montana west of the Continental Divide is often included as part of the region. Included in the region are the counties of:
Montana (Sometimes Included)
According to the U.S. Census Bureau, the estimated population as of 2004 was 1,913,682 making it, in population, comparable to New Mexico. Its Canadian counterpart, north of the border, is the British Columbia Interior.
The region is bounded by the Cascade Mountains on the west and the Rocky Mountains (following the spine of the remote and rugged Cabinet Mountains) on the east, the Blue Mountains (Oregon) and foothills of the Wallowa Mountains to the south, southeast, and encompasses the Columbia river basin (or Columbia Plateau). Between the three mountain ranges are large, sweeping areas of semi-arid steppe, part of which has been irrigated due to the Columbia Basin Project, resulting in expansive farmland in central Washington. The Palouse, original home of the Appaloosa, is another major agricultural region located in the gently rolling hills of southeastern Washington and extending into Idaho. In Idaho, the Silver Valley is a mineral rich region of the Coeur d'Alene Mountains in northern Idaho noted for its mining heritage, dating back to the 1880s.
