1970 Map of Bettles B-6

USGS Topo · Published 1977

About this map

The Koyukuk River and Kanuti River dominate this 1970 landscape, illustrating a remote Alaskan interior defined by its winding waterways and seasonal overland routes. The topography highlights the distinct Kanuti Canyon, where the river carves through the terrain, while the southern reaches feature a pingo, a characteristic permafrost-induced landform. Evidence of human passage is marked primarily by an extensive network of sled and foot routes, including the Allakaket Tanana Winter Trail, Allakaket Trail, and Tanana Trail. These pathways suggest the critical importance of winter travel in an era when permanent infrastructure was limited to occasional structures like the isolated Cabin found near the riverbanks. The map captures the region before more modern developments, preserving the layout of traditional trails and the undisturbed course of the Mentanontli River.
