About this map

Colville National Forest dominates this topographic survey of the Kettle River Range in Ferry County, where high ridges and steep drainages define the landscape. The map centers on significant peaks including Jackknife Mtn, Mack Mountain, and Graves Mountain, with the distinctive Alligator Ridge and Twin Sisters forming prominent silhouettes against the skyline. Narrow valleys are carved by the North Fork Deadman Creek and South Fork Boulder Creek, reflecting a wilderness defined by water and altitude.

Evidence of resource management and early recreation is visible through a network of 4wd roads and isolated clearings like the Borrow Pit. In the southeast, the terrain softens into the Hoodoo Canyon, where Lilly Lake and Emerald Lake sit at the base of Coyote Mountain. This 1990s record documents the forest's transition from mid-century timber access toward modern conservation and backcountry use, preserving the exact placement of survey markers like BM 2983 and primitive forest tracks.
