About this map

The Okanogan National Forest and Wenatchee National Forest converge in this high-elevation landscape above the northern reaches of Lake Chelan. The topography is defined by a series of prominent divides and drainage basins, most notably Cooper Ridge, which separates the complex system of gulches and canyons to the south from the Antoine Cr watershed. The map reveals a high-altitude network of forest development roads, such as Nat For Dev Rd 8210, that provide access to points like Goff Peak and Washington Butte.

Settlement patterns are concentrated in the lower elevations of Union Valley, where a grid of local roads like Homesteader Rd and Elmer Garton Rd suggests small-scale ranching or residential enclaves. This area contrasts sharply with the deep incisions of Purtteman Gulch and Brownfield Canyon, illustrating the transition from managed forest lands to the semi-arid valley floor common in North Central Washington.
