The Palouse River winds through the southern reaches of this landscape, marking a significant hydrological boundary at the convergence of Adams and Whitman Counties. This area is defined by its dramatic drainage patterns, where Cow Creek and ancient channels like Staley Coulee and Holliday Coulee carve through the terrain. The settlement of Hooper and the nearby Hooper Junction serve as focal points for the region's transport history, situated where traditional roads meet the long-distance corridor of the Columbia Plateau State Park Trail. This trail follows an older rail alignment, illustrating the shift from industrial transport to recreational use. Isolated water bodies like Lost Lake and Green Lake appear in the northern sections, while a network of rural routes including Mullen Rd and Benge Washtucna Rd connect the scattered ranching and agricultural sites like Ankeny.
