1950 Map of Big Delta A-5

USGS Topo · Published 1977

About this map

Fort Greely dominates this interior Alaska landscape at the confluence of glacial waters and major transport corridors. Originally mapped in 1950, this edition includes purple revisions from 1975 that capture the massive infrastructure push of the mid-century. Most prominent is the presence of The Trans-Alaska Pipeline (under construction) running parallel to the Richardson Highway and a Military Pipeline. The braiding channels of the Tanana River and Delta Creek create a complex network of wetlands and shifting sandbars, characteristic of the region's dynamic hydrology. Isolated Cabins near Clear Creek and landmarks like Vabm 1579 Top serve as essential reference points in this expansive territory of the Fairbanks Meridian. The transition from early Cold War military development to the modern energy era is clearly documented in the overlaid layers of pipeline and highway infrastructure.
