1956 Map of Black River B-2

USGS Topo · Published 1959

About this map

Salmon Fork Black River and the Grayling Fork Black River dominate this interior Alaskan landscape, which was mapped by the Geological Survey during the mid-1950s using photogrammetric methods. The terrain is defined by a dense network of meandering waterways and lake-filled lowlands that transition into the high ground of Big Mountain. This survey was conducted before roads or established trails reached this part of the Yukon-Koyukuk region, leaving the river systems as the primary conduits through the territory. Along the northern bank of the river, Pink Bluff stands as a distinct landmark against the surrounding wetlands and forested slopes, marking the topography of a region then accessible only by air or water.
