Cook Inlet dominates the southern reaches of this landscape, where tidal waters meet the sprawling drainage of the Susitna Valley. The environment is defined by a complex network of waterways, including the Susitna River, Ivan River, and the intricate Beluga Slough. This coastal wetland system creates distinct landforms such as Big Island and Barrel Island, which are situated within the shifting intertidal zones. The northern sections of the map are characterized by the vast alluvial deposits and marshes typical of the lower Susitna basin.
