About this map

The boundary between Yakima and Klickitat counties cuts through this high plateau landscape, defined by deep drainage systems and early rural infrastructure. Recorded by the Department of the Interior through 1960s photogrammetry, the map reveals a rugged network of water-carved features including the winding Glade Creek and the bifurcated paths of Coyote Canyon and Dead Canyon.

A landmark for local historians is the site of Plainview, positioned near the intersection of several unimproved routes. Early property access and transit are documented via family-named thoroughfares such as Wandling Road, Poeckes Road, and Smith Road. These labels, along with Alderdale Rd and Mercer Road, trace the movement of early settlers through the high country of South-Central Washington during the mid-twentieth century.
