The Innoko River winds through the southern reaches of this interior Alaskan landscape, defining the local drainage patterns within the Yukon-Koyukuk region. This 2015 survey by the U.S. Geological Survey captures the intricate network of wetlands and small water bodies that characterize the alluvial terrain. The map is primarily organized by the Public Land Survey System, showing the boundaries for t20s r3e, t20s r4e, t21s r3e, and t21s r4e. Without significant human settlements or industrial infrastructure shown, the topography reflects a remote wilderness dominated by natural hydrological features and subtle elevation changes.
