The mountain-edged settlements of Buxton and Manning anchor this survey of the northern Tualatin Valley foothills. The landscape is defined by the headwaters of West Fork Dairy Creek and its many tributaries, such as Mendenhall Creek and Whitcher Creek, which carve deep canyons including Poliwaski Canyon and Hares Canyon. Transportation history is visible through features like the Sunset Tunnel and a network of rural roads such as NW Bacona Rd and NW Genzer Rd.
