The Tualatin Mountains create a prominent divide between the industrial waterfront of the Willamette River and the expanding residential landscape of Washington County. Along the river, the historic community of Linnton and the St Johns district are linked by the St Johns Bridge, serving as anchors for a heavy industrial corridor featuring the Gasco plant and extensive rail infrastructure. To the west, the steep, wooded terrain of Forest Park gives way to the suburbanizing hills of Bonny Slope and Cedar Mill.
