About this map

Glade Cr winds through this arid section of the Horse Heaven Hills, carving deep drainages like Moore Canyon and Coyote Canyon. The landscape is defined by a strictly etched grid of rural tracks, including McKinley Springs Rd and Horrigan Rd, which navigate the high-elevation ridges between Yakima, Benton, and Klickitat counties. This 2020 survey by the U.S. Geological Survey reveals a modern agricultural and ranching environment where section lines dictate movement. These roads, such as Farnum Rd and Poeckes Rd, trace the high plateaus above the Columbia River basin, providing essential access to this high-desert terrain. The convergence of three county boundaries near Smith Rd highlights the administrative importance of this sparsely populated but topographically complex region.
