About this map

The Alaska Pipeline cuts through this interior landscape, marking a significant modern industrial corridor through the Copper River Census Area. The terrain is defined by an extensive network of freshwater bodies, including the centrally located Birch Lake and the northern expanse of Boulder Lake. In the northwest, Middle Lake sits near the edge of the survey area, while Ewan Lake dominates the western boundary.

Connecting these remote waters is the Sourdough Ewan Lake Trl, a route that reflects the ongoing importance of overland access in a region largely devoid of paved roads. To the northeast, the Gulkana River winds across the corner of the quadrangle, representing the primary drainage for this wetland-rich plateau. The layout of these features illustrates a wilderness characterized by high-latitude hydrology and the vital energy infrastructure of the northern frontier.
