About this map

The South Fork Koyukuk River winds through this subarctic interior, defining a landscape dominated by extensive wetlands and seasonal watercourses. This 2017 survey by the U.S. Geological Survey illustrates the hydrological complexity of the Yukon-Koyukuk region, where tributaries like Wilson Cr and Hidden Cr feed the primary river system. A prominent topographic landmark, Eagle Cliff, rises above the northern bank of the river, providing a significant navigational point in an otherwise undulating terrain of lowlands and marshes. The lack of road infrastructure on this sheet emphasizes the remote character of the Koyukuk drainage, where travel remains dictated by river corridors and the natural relief of the land.
