The Columbia River dominates the western edge of this landscape, separating the Washington and Oregon borderlands near the port city of Kalama. The river's influence is evident in the complex of islands and bars like Cottonwood Island, Sandy Island, and Hunter Bar, which shift alongside the Kalama Upper Range and Kalama Lower Range navigation channels. Inland, the terrain rises toward the volcanic peaks of the Cascade foothills, including Green Mountain and Battle Mtn.
