Within the United States, the Northwest includes most of Idaho, Washington, and Oregon states, and a portion of northern California. Ecologically speaking, the Northwest extends northward through Canada, and includes much of British Columbia and southeast Alaska. The Region contains the world’s largest temperate rainforest zone, stretching from Alaska to northern California. It also contains the Cascade Mountains (up to 14,000 ft. [4,300 m] in elevation), and the dry deserts of eastern Washington and Oregon. Our office is located 80 miles north of Seattle, WA and twenty miles south of the U.S.-Canadian border.
