1956 Map of Fort Yukon B-3

About this map

The Yukon River carves a complex path through this subarctic terrain, joined by a dense network of waterways including Seventeenmile Slough and Yabm Slough. This 1950s survey documents a landscape of shifting channels and low-lying islands, such as Twelvemile Island and Egil Island. The geography is defined by a heavy concentration of wetlands and lakes, with Ninemile Lake situated in the northern reaches of the quadrangle. Human presence is sparse, marked primarily by a single Cabin along the winding course of Birch Creek and a solitary Winter Trail cutting through the northwestern section. These features suggest a seasonal reliance on the landscape for trapping or subsistence, typical of the interior before more permanent infrastructure reached this part of the Yukon-Koyukuk region. Mapping control was provided by the U.S. Geological Survey and USC&GS, utilizing aerial photography to document the intricate drainage patterns.
