1950 Map of Mount Hayes D-4

About this map

The Fort Greely Military Reservation Boundary dominates the eastern and central portion of this landscape, reflecting a period of intense Cold War strategic development in interior Alaska. Established in the mid-20th century, the post is anchored by the Big Delta Arctic Training Center and supported by infrastructure including the CAA Station and Big Delta Airport. The Richardson Highway serves as the primary ground artery, cutting through the terrain alongside the braided channels of the Delta River. In the southern reaches of the map, Donnelly Dome rises as a prominent landmark above a terrain marked by numerous kettle lakes, such as Bolio Lake and Big Lake, and the drainage of Jarvis Creek. This survey captures the integration of military utility and natural geography before the expansion of later decades.
