The Tilton River and Cowlitz River valleys define the lower half of this Lewis County landscape, serving as the primary corridors for settlement and industry during the late 1950s. The town of Morton serves as a regional hub, complete with its Logging RR, High Sch, and industrial infrastructure like a Gas Tank and Sewage Disposal plant. Further west, the Cowlitz valley houses several small communities including Mossyrock, Ajlune, and Riffe—the latter situated along the river's path before later hydrological changes altered the valley floor.
