About this map

The Okanogan River carves through the western edge of this landscape, defining the corridor where settlements like Riverside and Barker are established. Moving east from the river, the terrain ascends into a series of high ridges and basins, including Chewiliken Valley and Meader Flat. This 2011 survey reveals a rural network of roads such as Tunk Creek Rd and Chewiliken Valley Rd that navigate the drainages of Tunk Creek and Chewiliken Creek.

Upland features such as Baker Mountain and Stowe Mountain dominate the central topography, while more secluded landmarks like Bob Neal Lake and Corral Lake suggest the isolated nature of the backcountry. Historically significant sites like McLoughlin Falls on the river and the inland Tunk Valley provide specific points of interest for those tracing the development of Okanogan County outside the primary river valley.
