The Yakima River flows through the northern reaches of this mid-1960s survey, marking the fertile transition between the Yakima Valley and the rising slopes of the Horse Heaven Hills. The settlement of Whitstran and the eastern edge of Prosser serve as the primary hubs, connected by the historic route of the Old Inland Empire Highway and the Northern Pacific railroad. The landscape is defined by its agricultural infrastructure, featuring an intricate network of irrigation systems including the Pacific Canal, several aqueducts, and a large siphon.
