1956 Map of Black River A-6

About this map

Big Creek defines the eastern corridor of this interior Alaskan landscape, winding through a complex network of wetlands and unnamed lakes during the mid-1950s. The terrain is characterized by a dense concentration of smaller water bodies and significant topographical relief, with numerous unnamed peaks exceeding 800 feet. This 1:63,360 scale survey provides an unblemished look at the region before modern infrastructure, as the margin notes confirm there were no roads or trails present in this area at the time of the 1956 field annotation. The intricate contour work reflects the raw hydrology of the Yukon-Koyukuk region, where the drainage patterns of Big Creek dominate the eastern basin.
