2017 Map of Poisel Butte SW

About this map

Horse Heaven Hills dominate the southern portion of this landscape, where the high ridges of Yakima and Klickitat counties meet. This 2017 survey shows a region defined by its rugged topography and a network of Bureau of Indian Affairs roads, including Bia RD 240 and Bia RD 260, which navigate the steep drainage systems of Mule-Dry Cr and Pine Cr. A notable point of local historical interest is the Onepennee Cem located in the eastern section near a landform identified as The Island. The mapping of seasonal water sources such as Rock Spring and Pine Spring illustrates the arid character of these uplands. This modern record provides a detailed view of current land management boundaries and road infrastructure in a sparsely populated section of the Yakima and Klickitat county border.
