1970 Map of Bettles D-1

About this map

The Trans-Alaska Pipeline cuts a distinct path through this interior Alaskan wilderness during its 1970s construction phase, marked on this sheet as being under construction. The landscape is defined by the complex drainage systems of the S Fk Koyukuk R and the Jim River, which wind through the terrain alongside numerous tributaries. Notable water features include the isolated Grayling Lake and the long courses of Prospect Creek and Douglas Creek. This survey captures a pivotal moment in the development of the Alaskan North Slope infrastructure, where industrial engineering began to intersect with the traditional hydrology of the Bear Creek and Davis Creek basins. The map provides a detailed view of the topographical contours and stream networks before the full completion of the pipeline corridor.
