The Columbia River dominates the southern reaches of this landscape, where the tidal influence is evident in the intricate network of channels including Seal Slough and Halaya Slough. The riverside economy and maritime history are anchored by landings and lights, such as Carlson Landing, Svensens Landing, and the Rocky Point Light. Moving inland, the terrain transitions into a complex drainage system fed by the Grays River and Deep River, where small communities like Rosburg and Oneida are connected by local roads named for early area residents.
