About this map

McKinley Springs and the drainage of Glade Cr anchor this high-plateau landscape where Yakima, Benton, and Klickitat counties converge. The terrain is defined by deep incisions like Moore Canyon and Coyote Canyon, which cut through the agricultural geometry of the region. A sparse network of gravel and section-line roads, including McKinley Springs Rd and Horrigan Rd, provides the primary access to these remote draws. The map illustrates a contemporary pattern of large-scale land management typical of south-central Washington, where seasonal water sources and topographic relief dictate the placement of ranch infrastructure and transportation corridors like Glade Creek Rd and Poeckes Rd.
