Saddle Mountains dominate the southern half of this landscape, rising above the Wahluke Slope and the Wahluke Branch Canal. The terrain is defined by the sharp transition from the elevated ridgeline down through Saddle Gap into the drainage of Lower Crab Creek. This area, situated along the border of Grant and Adams counties, is largely dedicated to conservation, with significant acreage managed as part of the Columbia National Wildlife Refuge and the Saddle Mountain National Wildlife Refuge. A network of local agricultural and access roads, such as Crab Creek Rd and Powerhouse Rd, trace the lowlands, reflecting a landscape managed for both water distribution and wildlife protection. The presence of the Crab Creek Wasteway underscores the region's complex hydrological systems used to manage runoff and irrigation within the arid central Washington environment.
