The Koyukuk River and the South Fork Koyukuk River dominate this interior Alaskan landscape, where the shifting hydrology of the subarctic takes center stage. This portion of the Yukon-Koyukuk region is characterized by an intricate network of oxbow lakes, abandoned river channels, and meandering tributaries that illustrate the constant movement of the water across the basin. The survey details the convergence of these major water systems within several townships, including t21n r20w and t20n r21w, showing a wilderness shaped entirely by natural forces. While void of permanent settlements or infrastructure, the map serves as a primary record for those studying the geomorphology of the Alaskan interior or the traditional navigation routes used along these significant northern waterways during the early 21st century.
