About this map

Boylston and Cheviot anchor this high-desert landscape in Kittitas County, where the topography is defined by the steep erosion of the Boylston Mountains and deep drainage networks. The map details a complex system of coulees and canyons, most notably Schnebly Coulee and Rocky Coulee to the north, and Middle Canyon and Johnson Canyon to the south. These features illustrate the characteristic scabland geology of the region, where seasonal water flow and ancient forces have carved distinct paths through the basalt.

Water sources are scarce but critical, evidenced by the presence of Poison Spring and Foster Spring, alongside seasonal flows like Whiskey Dick Cr and Johnson Cr. Transportation through this arid terrain follows established routes like the Vantage Hwy and the interstate corridor, cutting across the section lines of T17N R21E and T16N R21E. This survey provides a precise look at the rural intersections and topographical landmarks that have shaped ranching and travel in this part of Washington.
