2017 Map of Tule Prong

About this map

Horse Heaven Hills rise across this high-elevation landscape along the border of Yakima and Klickitat counties. The map captures a high plateau defined by deep drainage systems, including Tule Prong, Tule Canyon, and Dead Canyon. While much of the terrain is characterized by these dramatic breaks in the earth, the presence of the Glade Cem near Glade Cr provides a specific point of interest for those tracking family history in this corner of Washington. The road network, including Co Line Rd and Glade Rd, follows the section lines of the Public Land Survey System, illustrating how 19th-century land divisions continue to dictate the modern geography of the Pacific Northwest. These routes connect isolated ridges like Kimbrell Ridge to the wider region, crossing the complex network of canyons that feed toward the south.
