2023 Map of Chiliwist Valley

About this map

Chiliwist Valley and the small settlement of Olema define this portion of Okanogan County, where the landscape transitions from the protected timberlands of the Okanogan National Forest to managed water resources and ranching terrain. The topography is anchored by significant elevations such as Woody Mtn and Cook Mtn in the north, giving way to the deep incisions of Rowel Canyon further south. Water management is a primary feature of the valley floor, evidenced by the Stout Reservoir and the drainage network of Sullivan Creek and Chiliwist Creek. A network of forest and county roads, including Chiliwist Rd and Olema Rd, provides access to the high points and terminal landmarks like Rattlesnake Point. This survey details the modern layout of these remote mountain drainages, illustrating the continued reliance on the natural creek systems for local geography and naming.
