The Willamette River and Multnomah Channel define the industrial and maritime character of this region during the mid-twentieth century. Riverside settlements like Linnton, Harborton, and Miller sit at the base of the Tualatin Mountains, where heavy rail lines including the Spokane Portland and Seattle Ry and Burlington Northern serve the waterfront. A sharp geographic divide exists between the steep, wooded slopes of Forest Park and the rapidly expanding suburban developments to the south and west.
