(Main article: Spokane, Washington) The history of Spokane, Washington in the northwestern United States developed because Spokane Falls and its surroundings were a gathering place for numerous cultures for thousands of years. The area's indigenous people settled there due to the fertile hunting grounds and abundance of salmon in the Spokane River. The Inland Northwest was first explored by Canadian explorer-geographer David Thompson, working as head of the North West Company's Columbia Department. At the nexus of the Little Spokane and the Spokane, Thompson's men built a new fur trading post, which is the first long-term European settlement in Washington state.
