1950 Map of Talkeetna Mountains B-4

About this map

The Talkeetna Mountains define this high-altitude landscape as it was mapped by the Department of the Interior and the Geological Survey during the mid-twentieth century. This terrain is marked by a complex network of glacial valleys and alpine drainage systems, most notably the Talkeetna River and its major tributaries like Yellowjacket Creek and Iron Creek. The map reflects a period of intensifying aerial survey work, utilizing photogrammetric methods from 1951 and 1958 to complete earlier gaps in mapping. Surveyors relied heavily on triangulation stations such as VABM 6555 Xylic and VABM 6460 Sedan to establish elevation data across the remote interior. The dominance of hydrology, including the East Fork and Middle Fork Iron Creek, highlights the primary natural corridors through this roadless wilderness in the years following World War II.
