Spokane is a city located in the Northwestern United States in the state of Washington. It is the largest city and county seat of Spokane County, as well as the metropolitan center of the Inland Northwest region. The city is located on the Spokane River in Eastern Washington, 110 miles south of the Canadian border, approximately 20 miles from the Washington-Idaho border, and 271 miles east of Seattle. David Thompson explored the Spokane area and began European settlement with the westward expansion and establishment of the North West Company’s Spokane House in 1810. This trading post was the first long-term European settlement in Washington and the center of the fur trade between the Rockies and the Cascades for 16 years. In the late 1800s, gold and silver were discovered in the Inland Northwest. The Spokane area is considered to be one of the most productive mining districts in North America.
