About this map

The Okanogan River carves a deep valley through this portion of Okanogan County, creating a landscape defined by significant elevation changes and seasonal water sources. The river is marked by riverine features such as McLaughlin Falls and McAllister Rapids, which historically influenced navigation and settlement patterns in the region. To the east, the terrain rises sharply into a series of named peaks and ridges, including Stowe Mtn and Lockman Ridge. The small settlements of Keystone and Tunk Valley are situated along the lower slopes, connected by a network of rural routes like Tunk Creek Rd and Keystone Rd. This area is characterized by numerous springs and small upland lakes, such as Bob Neal Lake and Corral Lake, which suggest a reliance on these scattered water points for ranching or local survival in the high country between Chewiliken Valley and Meader Flat.
