The Cosna River winds through the northern portion of this interior Alaska wilderness, serving as the primary geographic landmark for this unpopulated sector of the Yukon-Koyukuk Census Area. The terrain is characterized by a dense network of ridges and drainage basins, meticulously charted with twenty-foot contour intervals that reveal the complex hydrology of the region. Surveyed as part of the Public Land Survey System, the map details the boundaries of townships t5s r21w, t5s r20w, t6s r21w, and t6s r20w. This 2017 edition reflects the state of this subarctic landscape in the early twenty-first century, showing a region devoid of roads or settlements, where the natural course of the river dictates the topography.
