About this map

Fort Greely and the strategic convergence of the Alaska Highway and Richardson Highway dominate this landscape during a period of significant infrastructure development. The map details the vital transportation corridors through the Interior, following the winding courses of the Tanana River and Delta River. This 1950s-era topography, updated with later revisions, shows the coexistence of military installations like Allen Airfield alongside remote outposts such as Jollys Cabins and Bluff Cabin.

Energy and logistics are central to this area, highlighted by the presence of The Trans-Alaska Pipeline and the Military Pipeline. From the wetlands of Shaw Creek Flats to the hunting and fishing grounds around Quartz Lake and Clearwater Lake, the map traces the intersection of wilderness and modern utility. Settlement patterns at Delta Junction and Big Delta reflect the importance of river junctions and road intersections in Alaska's development.
