Umtanum Ridge and Yakima Ridge define the landscape of this region, which was surveyed in the late 1940s before significant modern alteration. The northern edge of the map is dominated by the Columbia River, where the Chicago Milwaukee St Paul and Pacific railroad tracks trace the shoreline near China Bar. This area of central Washington reflects a sparse, ranch-oriented settlement pattern, anchored by the Roberts Ranch in the south.
