Sheridan and Willamina anchor this mid-century look at the border of Yamhill and Polk counties. The South Yamhill River serves as the primary drainage and industrial corridor, supporting the Millponds near the confluence of Willamina Creek. Transportation is well-defined by the Southern Pacific and Longview Portland and Northern railroads, which parallel the river and the Pacific Highway through Shipley.
