About this map

The town of Washtucna sits at the northern edge of this quadrangle, where the massive geological trench of the Washtucna Coulee dominates the local topography. This arid region of southeastern Washington, spanning the boundary of Adams and Franklin Counties, is characterized by the complex channelled scablands. Local life is anchored by family-held agricultural operations such as the H U Ranch, Davin Ranch, and Howard Ranch, which utilize the flat valley floors of the coulees between steep basalt walls.

Surface water is sparse in this high desert landscape, with Deep Lake and the smaller Holliday Coulee providing notable geographic interruptions to the basalt plateaus. Transportation in the area follows these natural corridors, with Wa-261 and Wa-260 tracing the low ground. Rural access is maintained via established routes like Nunamaker Rd, Davin Rd, and the road leading toward the falls at Palouse Falls Rd.
