About this map

The Tanana River dominates the southern landscape of this Interior Alaska region, serving as the primary geographical anchor for a network of northern tributaries. The waterway forms a natural boundary between the Fairbanks North Star Borough and the Southeast Fairbanks Census Area. Cutting across the central terrain, the Richardson Highway provides the essential overland link, following the contours of the land just north of the river. This alignment illustrates the classic corridor development of the Alaskan Interior, where modern transportation infrastructure mirrors the ancient paths carved by water. Numerous seasonal and perennial streams like Banner Creek and Junction Cr drain the uplands, highlighting a complex hydrological system that defines the local topography and historical access routes into the surrounding wilderness.
