The Willamette River and Multnomah Channel define the eastern edge of this landscape, separating the industrial corridors of Portland and Saint Johns from the broader Tualatin Valley. The transition from the riverfront heights of the Tualatin Mountains to the expanding residential grids of Bethany, Cedar Mill, and Cedar Hills illustrates the late 20th-century development patterns in the west hills. Genealogists will find a high concentration of burial grounds, including the Bethany Methodist Cem and the Pioneer Catholic Cem of Saint Anthony of Padua. Notable infrastructure like the Saint Johns Bridge and the Cornelius Pass road network link the agricultural remnants of the valley with the maritime activity at Doane Point and the Columbia Slough. Educational institutions such as the Portland Community College Rock Creek Campus anchor the suburban growth seen in Oak Hills and Bonny Slope.
