1956 Map of Black River C-2

About this map

Salmon Fork Black River defines the southern boundary of this interior Alaskan landscape, winding through a corridor of low-lying wetlands and complex drainages. Based on aerial photography from 1955 and field annotations from 1956, this survey illustrates a remote wilderness defined by water and elevation rather than human settlement. The drainage of Tetthajik Creek dominates the eastern and central portions of the sheet, connecting a series of unnamed lakes and marshes that suggest a highly seasonal and shifting aquatic environment. The lack of roads or established trails in this area at the time of mapping underscores the isolation of the Yukon-Koyukuk region, where travel was likely dictated by the seasonal flow of the river systems. This map serves as a primary record of the natural topography before modern navigation or environmental changes altered these northern waterways.
