The Gulkana River flows through the western edge of this sub-arctic landscape, defining a remote interior drainage system in the Unorganized Borough. This 2016 survey documents the intricate water network surrounding Alder Lake and the lower Caribou Lake, where high-elevation wetlands dominate the terrain. Unlike developed regions, the area is characterized by its hydrography rather than human settlements, with Sinona Cr and Excelsior Cr carving paths through the high country. The map provides a detailed look at the Public Land Survey System grid across T21S and T22S, capturing the raw topography of the Alaska Range's southern slopes before any modern infrastructure altered the drainage patterns.
