Fort Okanogan State Park, Washington

Fort Okanogan was founded in 1811 on the confluence of the Okanogan and Columbia Rivers as a fur trade outpost. Originally built for John Jacob Astor’s Pacific Fur Company, it was the first American-owned settlement within Washington state, located in what is now Okanogan County. The North West Company, the PFC's primary competitor, purchased its assets and posts in 1813. In 1821 the North West Company was merged into Hudson's Bay Company, which took over operation of Fort Okanogan as part of its Columbia District. The fort was an important stop on the York Factory Express trade route to London via Hudson Bay.
