1958 Map of McGrath C-1

About this map

Dillinger River and the Big Salmon Fork define this interior Alaska landscape, captured through aerial photography in the late 1950s. The terrain is characterized by a dense network of glacial meltwater streams and braided river channels, particularly where the Jones River flows through the southwestern reaches. A single Tractor Trail provides the only evidence of overland passage through this remote stretch of the Matanuska-Susitna Borough boundary. The map illustrates the complex drainage patterns of Deepbank Creek as it feeds into the larger river systems, revealing a wilderness essentially untouched by permanent settlement or infrastructure at the time of the survey.
