2017 Map of Black Rock Spring NE

About this map

Umtanum Ridge dominates this arid landscape at the boundary of Kittitas and Yakima counties. This 2017 survey details the complex topography of the ridge as it transitions into a series of deeply carved geographic features including Alkali Canyon, Corral Canyon, and Cow Canyon. The presence of the Hog Ranch Buttes in the southwestern quadrant provides a distinct landmark against the surrounding terrain. Unlike more developed regions, this map shows a landscape largely defined by its natural relief and drainage patterns, such as Sourdough Canyon, illustrating the remote character of this part of central Washington. The high-resolution contour data from the National Elevation Dataset provides a precise view of the various draws and ridgelines that characterize the area's geological structure.
