1991 Map of Rye Grass Coulee

About this map

Rye Grass Coulee cuts through this arid stretch of Franklin County, showing a landscape defined by dramatic geological formations and remote infrastructure at the start of the 1990s. The map illustrates a high-desert environment where natural features like Smith Canyon and Blackman Ridge Road are the primary landmarks. In the southeastern corner, the Juniper Dunes Wilderness begins to emerge, highlighting a protected pocket of shifting sands and native vegetation. Small-scale industrial activity is evidenced by a Sandpit and scattered Storage Bins, while a prominent Pipeline and several unimproved tracks like Blanton Road and Stastney Road navigate the ridges. This survey is particularly useful for understanding the rural road network and topography of the Washington interior before modern development intensified in the Columbia Basin.
