1956 Map of Black River B-6

About this map

Grass River and the Little Black River dominate this interior Alaska landscape, weaving through a dense network of marshes and oxbows. The intricate hydrology of the region is further defined by the Vunle Lakes in the north and the isolated Mardow Lake to the southwest. This 1950s survey captures a transition in northern transportation, where traditional water routes like the Sucker River and Big Creek are supplemented by primitive Tractor Trails cutting across the upland areas. These trails represent the primary overland infrastructure of the era, connecting the remote drainage basins of Tiechovun Lake with the broader river systems that served as the lifelines for movement through the Yukon-Koyukuk region.
