Telsitna River meanders through this interior Alaska landscape, providing the primary drainage for the surrounding basins. This 2019 survey documents the intricate topography of the Yukon-Koyukuk Census Area, centered on the boundary between t16s r26e and t16s r27e. The map illustrates the complex drainage patterns of this subarctic environment, where the river valley cuts through elevations ranging from 700 to over 2,200 feet. The Public Land Survey System grid provides a structured overlay for this largely undeveloped terrain, including the transition into t17s r26e and t17s r27e.
