Nine Canyon and Switzler Canyon dominate this part of Benton County, carving deep drainage patterns through the upland terrain south of the Columbia River. The map, based on 1959 aerial photography and field-checked in the mid-1960s, reveals a landscape defined by agricultural infrastructure and early transport networks. A series of irrigation features, including a Canal and multiple Siphons, supports the dryland farming indicated by the presence of a Storage Bin. This network of water management was essential for local production in this arid climate.
