2017 Map of Chiliwist Valley

About this map

Olema and the Chiliwist Valley serve as the primary focal points of this Okanogan County landscape, where the terrain shifts from the wooded uplands of the Okanogan National Forest to agricultural basins. The valley is defined by the convergence of several waterways, including Chiliwist Creek, Sullivan Creek, and Whitestone Creek, which have historically shaped the settlement patterns and road networks. High elevation landmarks like Woody Mountain and Cook Mountain overlook a complex system of local routes such as Golden Rule Road and Lower Thrapp Mountain Road. This 2017 survey highlights the area's ongoing reliance on water management, evidenced by the Stout Reservoir, while geological features such as Rowel Canyon and the prominence of Chiliwist Butte reflect the region's diverse topography.
