1958 Map of Tyonek B-3

About this map

Theodore River and the Lewis River dominate this 1958 survey of the Alaskan wilderness, carving through the lowlands where the Matanuska-Susitna and Kenai Peninsula Borough boundaries meet. The map documents an era of early resource exploration and remote subsistence, marked by numerous Drill Holes and isolated structures like Grants Cabin. The drainage network is dense, including Pretty Creek, the Chedatna River, and the Ivan River which feeds into the Ivan Lakes. Evidence of seasonal transport and industry is visible at the Winter Landing Strip and a solitary Mine in the northern highlands. The landscape transitions from the higher elevations of Wolverine Creek down to the broad marshes of the Beluga River and the tidal influence of the Lewis River Slough, illustrating a complex hydrologic system before major modern development.
