South Fork Koyukuk River meanders across this northern landscape, defining a complex network of wetlands and seasonal watercourses in the central Yukon-Koyukuk region. The area is characterized by the convergence of major glacial drainage systems, where the river's broad floodplains meet the winding path of the Jim River. Detailed topographic contours illustrate the gradual elevation changes between the river basins and the surrounding upland plateaus. This 2016 survey captures the wild hydrology of the Alaskan interior before the seasonal shifts and natural erosion typical of these arctic river systems further alter the channel paths.
