2020 Map of Cayuse Mountain

About this map

Aeneas Valley sits at the heart of this Okanogan County landscape, where the waters of Bonaparte Cr and Patterson Cr drain the surrounding highlands. This modern survey illustrates a rugged corner of the Okanogan National Forest, defined by significant elevations such as Cayuse Mtn and the appropriately named Fourth of July Ridge. The drainage patterns are intricate, featuring the branching network of Siwash Cr with its North, Middle, and South forks. A complex web of access roads, including Cayuse Mountain Rd and Aeneas Valley Rd, traces the contours of the terrain, providing a detailed view of how contemporary land management and recreation interface with the natural topography. From the high reaches of Bigham Flat to the creek beds of Peony Cr and Erle Cr, the map provides a precise record of the current physical and naming conventions in this remote Washington wilderness.
