2013 Map of Rye Grass Coulee

About this map

Rye Grass Coulee and Smith Canyon dominate this arid portion of the Columbia Basin in Franklin County, where the landscape is defined by deep drainage systems and long ridgelines. The area shows a sparse network of service roads and land management divisions, including Blackman Ridge Rd and Statney Rd, which navigate the elevation changes between the coulee floor and the surrounding plateaus. The topography here reflects the distinctive geologic erosion of the region, captured shortly after the turn of the millennium. The survey provides a clear view of how rural infrastructure like Smith Canyon Rd and E Elm Rd aligns with the section lines of the Public Land Survey System, a vital reference for property researchers and local historians studying the rural development of this central Washington territory.
