About this map

Ninemile Flat and Rima Flat define the terraced topography above the Columbia River in this section of Ferry County. The landscape is dominated by the drainage systems of Ninemile Creek and its tributaries, including South Fork Ninemile Creek and Little Ninemile Creek, which cut through the high elevations of Gold Mountain Ridge. The impoundment of the river is visible as the Franklin D Roosevelt Lake, which is bordered by the Lake Roosevelt National Recreation Area.

A network of Bureau of Indian Affairs roads, such as Bia RD 1069 and Ninemile-Hellgate Rd, provides access to this portion of the Colville Indian Reservation. Significant elevation changes are marked by landmarks like Dodge Point and Mitchell Point, while Ninemile Falls indicates the sharp descent of the creek as it approaches the river valley. The map also records the jurisdictional boundary along the river between Stevens Co and Ferry Co.
