Frenchman Hills dominates the central portion of this landscape, rising above the agricultural lands of the Royal Slope to the south. This modern survey illustrates the intensive water management systems of the Columbia Basin Project, characterized by the West Canal and the complex drainage of the Winchester Wasteway and Frenchman Hills Wasteway. These features define the transition from high desert terrain to irrigated farmland. For those researching local heritage, the Pleasant Valley Cem stands as a notable landmark near Rd 11 SE. The map also traces the local transportation network including Royal Camp Rd SE and O'Sullivan Dam Rd, which connect the scattered rural homesteads and irrigation infrastructure like the Crab Creek Lateral.
