2017 Map of Black Rock Spring NW

About this map

Umtanum Ridge dominates this portion of the interior Northwest, showing a landscape defined by significant elevation changes and the drainages of the Yakima River watershed. The boundary between Kittitas Co and Yakima Co cuts across the northern third of the map, providing a fixed reference for land ownership and administrative history in the region. The terrain is marked by the presence of Hog Ranch Buttes, a prominent landform that overlooks the surrounding seasonal watercourses like Selah Cr and Umuma Cr. These features illustrate the arid, high-desert character of central Washington, where the physical geography has historically dictated the routes of travel and the limits of settlement.
