Columbia River waters held by the McNary Dam form Lake Wallula, dividing the states of Washington and Oregon in this early 1960s study. Along the northern bank in Benton County, the Spokane Portland and Seattle railroad tracks follow the shoreline through Berrian, while the southern Oregon side is dominated by the Union Pacific line and the recreational grounds of Hat Rock State Park. Notable basalt formations like Hat Rock and Boat Rock stand as landmarks near the mouth of Cold Springs Wash.
