1950 Map of Big Delta A-5

About this map

Fort Greely anchors the southern portion of this mid-century Alaskan landscape, marking a period of significant military and infrastructure development in the Interior. The confluence of the Tanana River and Delta Creek dominates the hydrology, while the Richardson Highway provides the primary corridor for movement. This edition is particularly notable for capturing a major transition in American energy history, showing the Trans-Alaska Pipeline while it was still under construction, running parallel to the existing Military Pipeline. Remote Cabins and a lone Cabin near Clear Creek provide evidence of early habitation amidst the wetlands and lakes, such as Rainbow Lake. Survey markers like VABM 1579 Top and its counterpart VABM 1579 Low document the precise work of the U.S. Geological Survey during this era of northern expansion.
