Harker Canyon (Washington)

Harker Canyon is formed by a tributary of the Spokane River, where it forms the Spokane Arm of Franklin D. Roosevelt Lake, in Lincoln County, Washington, United States. A small portion of the canyon where it empties into the Spokane River is part of the Lake Roosevelt National Recreation Area. The remainder of the canyon is private land.
