1958 Map of McGrath C-1

About this map

The Big Salmon River and its tributaries carve a complex drainage system through this interior Alaskan wilderness as it appeared in the late 1950s. The landscape is defined by the convergence of major glacial-fed water systems, including the wide paths of the Dillinger River and the Jones River. While much of the terrain is dominated by these waterways and high peaks, a single Tractor Trail provides a physical record of mid-century overland access through the region. This 1958 field-annotated study reveals the intricate braided channels and floodplains of the Deepbank Creek watershed, illustrating the dynamic nature of Alaskan river morphology before modern development.
