About this map

The Colville Indian Reservation dominates this 1980s landscape, where the high country of Gold Mountain Ridge descends into the broad Ninemile Flat near the eastern boundary of Ferry County. The terrain is defined by a dense network of drainages, including the South Fork and Little Ninemile Creek, which flow toward the massive expanse of Franklin D Roosevelt Lake. This impoundment of the Columbia River forms a significant portion of the Coulee Dam National Recreation Area, altering the original riverine environment into a vast reservoir system.

Evidence of early infrastructure and settlement is scattered along the slopes and flats, from the Borrow Pit north of the main creek to the site at Jensen near the water's edge. The map captures the area as it appeared following the completion of the Grand Coulee Dam, showing how modern recreation and reservation life intersect along the rugged shoreline at Mitchell Point and the turbulent waters of Ninemile Falls.
