2013 Map of Black Rock Spring NE

About this map

Umtanum Ridge dominates the southern landscape of this 2013 survey, which documents the high desert terrain where the Kittitas Co and Yakima Co border divides the high country. This arid region is defined by a series of significant drainage systems, including Alkali Canyon and Corral Canyon in the west, and the steep Sourdough Canyon and Cow Canyon to the east. Human presence in this high-altitude environment is anchored by the Stewart Ranch, situated in the center of the quadrangle. The topography rises sharply to the Hog Ranch Buttes, showing the elevation changes and land-use patterns common in central Washington’s rangelands. The map provides a precise record of the road networks and public land survey system lines that organize this corner of the state.
