1950 Map of Mount Hayes D-5

About this map

Fort Greely dominates the central landscape of this interior Alaskan territory, established as a military reservation during a period of strategic post-war expansion. The terrain is defined by the massive glacial braided systems of the Delta River to the east and Delta Creek to the west, where wide gravel beds and shifting channels illustrate the dynamic hydrology of the Alaska Range foothills. Small alpine tributaries like Ptarmigan Creek and Hayes Creek cut through the western ridges, feeding into the larger drainage basins. The lack of established roads or permanent settlements outside the military boundaries highlights the remote nature of this wilderness at the mid-century, primarily utilized for government operations and mapping by the Bureau of Land Management and Geological Survey.
