1989 Map of Seventeenmile Mountain

About this map

Colville Indian Reservation land occupies the southern portion of this landscape, meeting the Colville National Forest at the National Indian Forest Reservation Boundary. This 1989 provisional survey, based on 1983 aerial photography, illustrates a remote mountainous terrain in Ferry County defined by massive summits like Seventeenmile Mountain and South Seventeenmile Mountain. The drainage patterns are clearly delineated, showing the headwaters of Seventeenmile Creek and the West Fork Hall Creek as they carve through the high elevations. The map reveals the intricate network of forest roads and trails that provided access to these peaks and the eastern slopes of Grizzly Mtn. This document serves as a detailed record of late-20th-century forest management boundaries and topographical details before subsequent environmental changes in the Pacific Northwest.
