2014 Map of Cayuse Mountain

About this map

Okanogan National Forest dominates this section of the Highlands, where the drainage of Siwash Cr meets the northern reaches of the Aeneas Valley. The landscape is defined by its significant relief, rising from the valley floor to the heights of Cayuse Mtn and the prominent Fourth of July Ridge. Historically, this area has been characterized by its forestry and ranching heritage, with a network of access routes like Siwash Creek Rd and Patterson Creek Rd connecting remote homesteads and allotments. The map detail highlights how local topography dictated development, with early settlement and transit corridors following the natural paths carved by Bonaparte Cr and Patterson Cr. Traces of earlier mountain life are visible through the naming of landforms such as Island Mtn and the high plateau of Bigham Flat.
