2017 Map of Alpowa Ridge

About this map

Alpowa Ridge dominates this corner of the Pacific Northwest, where the high plateaus of Garfield and Asotin Counties are deeply incised by a network of gulches and canyons. Small settlements like Smith Gulch and Pataha Valley are established along the valley floors, connected by a winding rural road network including Kirby Mayview Rd and Sweeney Gulch Rd. This 2017 survey illustrates the complex drainage systems typical of the region, where seasonal waters such as Pataha Cr and Alpowa Cr carve through the basaltic layers of the landscape. Strategic water sources, including Dresser Spring and Kaufman Springs, appear as critical landmarks for local land use. The map also traces prominent geological features like Valentine Ridge and Knotgrass Ridge, providing a clear view of the topographic boundaries and elevation changes that define this remote high-country terrain.
