The confluence of the Columbia River and the Sanpoil River Arm anchors this high-elevation landscape within the Lake Roosevelt National Recreation Area. The map reveals the dramatic geography of Franklin D Roosevelt Lake, where rising waters have filled deep channels to create features like Moonbeam Bay, Covington Cove, and Ching Bay. The terrain is defined by steep elevation changes, rising from the water to high points such as China Bluff and Camel Bluff, with drainage provided by seasonal courses through Penix Canyon and Speigle Canyon. Transport and access are tied to the water's edge, notably at Keller Ferry and the adjacent Keller Ferry Campground. Local infrastructure consists of winding roads like Swawilla Basin Rd and Williams Flat Rd, which navigate the complex topography and connect small landings across the Ferry and Lincoln County line.
