North Twin Lake and South Twin Lake dominate the eastern edge of this landscape in Ferry County, where the topography rises sharply into the high ridges of the Colville Indian Reservation. The map documents a complex drainage system defined by Beaver Dam Cr and Granite Cr, which flow through the steep terrain between Oregon City Ridge and Carson Mtn.
