1958 Map of Tyonek B-1

About this map

The Little Susitna River winds through a complex wetland landscape in the late 1950s, characterized by the expansive Susitna Flats and the nearby Knik Arm. This survey illustrates a remote region where development is limited to isolated survival and aviation infrastructure, including a Landing Area with radio tower tanks and scattered Cabins. The terrain is dominated by a dense network of water bodies such as Horseshoe Lake, Twin Island Lake, and Yohn Lake, which are interconnected by drainages like Fish Creek and Maguire Creek. Surface transportation is represented by a solitary Tractor Trail cutting through the northern and eastern reaches, reflecting the era's reliance on specialized vehicles and aircraft to navigate the marshy ground and tidal Mud flats.
