About this map

The convergence of the Tanana River and the Delta River serves as the focal point for this interior Alaskan landscape, which highlights the critical transportation and military infrastructure of the mid-20th century. At the heart of the region sits Delta Junction, the historic terminus of the Alaska Highway where it meets the Richardson Highway. This strategic location is further emphasized by the presence of Fort Greely and Allen Airfield, alongside a decommissioned Military Pipeline and the later addition of The Trans-Alaska Pipeline.

Beyond the military and transit hubs, the map details the expansive Goodpaster Flats and Shaw Creek Flats, illustrating a terrain defined by braided river systems and numerous water bodies such as Quartz Lake and Clearwater Lake. Remote outposts and seasonal sites like Jollys Cabins and several landing strips appear along the waterways, reflecting the region's reliance on bush aviation and river access during the early post-war era.
