1958 Map of Tyonek B-1

About this map

Little Susitna River meanders through a vast expanse of wetlands and muskeg as it approaches the coast in this 1950s-era topographical record. The landscape is defined by its complex hydrology, featuring numerous isolated water bodies such as Diamond Lake, Yohn Lake, and Horseshoe Lake. Along the coast, the Susitna Flats meet the glacial waters of the Knik Arm, where tidal influences are noted by the presence of mud flats. Human activity in this period appears limited to scattered cabins and a rudimentary transport network consisting of several instances of a Tractor Trail. Evidence of mid-century aviation and communication infrastructure is visible near the river's center, where a Landing Area and a Radio Tower (AUN) are situated, likely supporting early regional surveying or logistics efforts.
