The Fortymile River carves a winding path through the heart of the Southeast Fairbanks Census Area, serving as the central drainage for a dense network of creek systems. This modern U.S. Geological Survey topographic study documents the complex hydrology of the region, where numerous named tributaries such as O'Brien Cr and Polly Cr descend from the high ridges. The lack of roads or established settlements on this sheet highlights the wilderness character of the interior, defined by the township and range lines of the Public Land Survey System. Researchers can trace the narrow valleys of Dick Dale Cr and Steele Cr as they feed into the main river channel, illustrating the undisturbed drainage patterns of this Alaskan landscape.
