Saddle Mountains dominate the southern landscape of this Grant County region, marking a dramatic shift from the riparian lowlands to the elevated Wahluke Slope. The small settlement of Corfu sits at the foot of these heights, positioned near the meandering course of Lower Crab Creek. This area is defined by a massive intersection of conservation lands, including the Columbia National Wildlife Refuge, the Saddle Mountain National Wildlife Refuge, and the northern edge of the Hanford Reach National Monument. The map reveals the intricate water management of the Columbia Basin Project, where the Wahluke Branch Canal and the White Bluffs Wasteway redirect water through the arid terrain. For researchers, the grid of rural roads like Crab Creek Rd and Rd A SE provides a precise look at the modern boundaries of these protected natural areas.
