2020 Map of Prosser SW

About this map

The high desert plateau of southern Washington defines this landscape, where the seasonal drainage of Glade Cr carves through the terrain as it moves toward the Columbia River basin. This survey highlights the rural infrastructure of the early 21st century, centered on the boundary between Yakima and Klickitat counties. Land use in this arid region is marked by a sparse network of long thoroughfares like Alderdale Rd and Smith Rd, which follow the natural contours of the ridges and draws. In the southeastern portion of the quadrangle, the land descends into the distinct geological formation of Coyote Canyon. The map reveals the persistence of the Public Land Survey System, with township and range lines like t7n r23e dictating the placement of secondary routes such as Poeckes Rd and Raschko Rd.
