About this map

Umtanum Ridge dominates the southern portion of this high-desert landscape in central Washington, where the boundary between Kittitas and Yakima counties cuts across the northern slopes. The terrain is defined by a series of significant drainages including Alkali Canyon, Corral Canyon, and Cow Canyon, which carve through the volcanic plateau. Near the western edge, the elevated summits of the Hog Ranch Buttes provide a distinct topographical landmark above the surrounding deep-cut ravines such as Sourdough Canyon. The lack of named settlements or modern infrastructure underscores the remote character of this region, which remains largely defined by its natural landforms and the established Public Land Survey System grids.
