2023 Map of Stember Creek

About this map

Stember Creek and Alpowa Creek carve through the high basaltic plateaus of this corner of southeast Washington, where the boundary between Garfield Co and Asotin Co follows the jagged path of local topography. The landscape is defined by its deep drainage systems, including Deadman Gulch and Davis Canyon, which cut through long elevated features like Alpowa Ridge and Knotgrass Ridge. These landforms dictate the region's sparse transportation network, with roads like Howell Grade Rd and Alpowa Creek Rd following the natural contours of the ridges and valley floors.
