The Columbia River serves as the central artery for this region, winding past the riverfront communities of Saint Helens and Scappoose as it approaches the mid-1990s. The landscape is defined by the complex aquatic network of the Multnomah Channel and Cunningham Slough, which separate the mainland from the northern tip of Sauvie Island. This area remains a crucial ecological and industrial corridor, evidenced by the expansive Ridgefield National Wildlife Refuge on the Washington shore and the Scappoose Industrial Airpark to the west.
