1970 Map of Bettles B-6

USGS Topo · Published 1973

About this map

The Koyukuk River and its southern tributary, the Kanuti River, dominate this subarctic landscape mapped in 1970. The geography is defined by the winding passage through Kanuti Canyon, where the river cuts through the uplands before entering broader valley floors. This area remains largely undeveloped, characterized by a network of seasonal transport routes rather than permanent settlements. Key overland routes include the Allakaket Tanana Winter Trail and the Mentanontli River Trail, illustrating how the region was navigated during the colder months when the terrain was frozen and traversable. The inclusion of a Pingo near the southern boundary provides a specific cryospheric detail, identifying a perennial frost mound characteristic of this permafrost-rich environment.
