1970 Map of Bettles B-1

About this map

The Trans-Alaska Pipeline (Under Construction) cuts a definitive path through this interior landscape, documented here during its mid-1970s construction phase. The route follows the terrain southward from Olsons Lake, crossing the meandering Kanuti River and traversing the drainage of the West Fork Dall River. This survey captures a critical moment in the development of the Alaskan infrastructure, where modern industrial engineering meets a traditional network of seasonal transit. A Winter Road and various sections of Winter Trail parallel or intersect the pipeline corridor, indicating how the region was navigated before permanent all-weather roads were established. The presence of Coal Creek and numerous unnamed basins reflects the complex hydrology of this subarctic environment, which the Bureau of Land Management oversaw during this period of rapid change.
