2020 Map of Poisel Butte SW

About this map

The Horse Heaven Hills dominate this high-desert landscape in south-central Washington, where seasonal drainages and natural springs dictate the geography of the land. This 2020 edition documents a remote section of the Yakima and Klickitat County border, characterized by an extensive network of Bureau of Indian Affairs routes like BIA Rd 240 and BIA Rd 260. For genealogists and local historians, the presence of the Onepenne Cemetery near the eastern margin provides a specific point of interest within the broader terrain. The map's hydrography is defined by intermittent features such as Mule Dry Creek and Bull Creek, alongside vital water sources like Rock Spring and Pine Spring. Significant elevation changes are marked by landforms like The Island, while the southern reaches are accessed via Shinando Canyon Road and Pine Creek Road.
