2011 Map of Rye Grass Coulee

About this map

Smith Canyon and Rye Grass Coulee define the drainage and topography of this Franklin County landscape, reflecting the geologic history of eastern Washington. This 2011 survey illustrates a sparse, agricultural infrastructure characterized by a grid of rural routes such as Statsney Rd, Blanton Rd, and Blackman Ridge Rd. A notable modern landmark is the Columbia Ag 2 Airport, situated in the southwestern corner of the quadrangle. The naming of roads like Smith Canyon Rd and Hummel Ln suggests the lineage of local landowning families who established the homesteads and farming operations in this arid region. The map provides a clear view of how irrigation and agricultural access have shaped the placement of roads like E Elm Rd around the natural coulees.
