About this map

The Innoko River snakes through this remote Alaskan interior landscape, defining a complex network of wetlands and tributary drainages during the mid-1950s. This survey records a vital moment in subarctic transport, where seasonal movement relied on the Winter Trail and Summer Trail corridors that connected isolated outposts. Small-scale aviation and river access supported the few established points of human activity, most notably at Cripple Landing along the riverbank and the settlement of Folger.

Beyond these riverside hubs, the terrain rises sharply toward the Cripple Creek Mts and Hunch Mountain. A rugged industrial footprint is evidenced by the Bear Creek No 1 Landing Strip, serving the drainage basins of Colorado Creek and Cripple Creek. The map provides a precise look at the hydrology of the Yukon-Koyukuk region, charting numerous named flows like Fourmile Creek and McLean Creek as they feed into the wandering Innoko.
