1985 Map of Keystone Peak

About this map

Clark Fork winds through the heart of this terrain, defining the local topography as it flows past Donlan Flats and the small settlement of Donlan. The landscape is dominated by the steep, timbered reaches of the Lolo National Forest, where numerous drainages like Sesame Creek and Patrick Creek descend toward the river. In the southern portion of the quadrangle, the high point of Keystone Peak stands over the settlement of Keystone, situated near the headwaters of Keystone Creek.
