2017 Map of Bettles D-1 NW

About this map

The Alaska Pipeline and the Dalton Highway serve as the primary human corridor through this part of the Yukon-Koyukuk Census Area. These critical infrastructure lines run parallel through the center of the sheet, traversing a landscape defined by the drainage systems of the South Fork Koyukuk River and the Jim River. This 2017 survey illustrates the intersection of modern industrial logistics with the natural geography of the interior, where the pipeline must navigate the topographical shifts between Grayling Lake and various tributary streams. The presence of Grayling Cr and Bear Cr suggests a region defined by seasonal water flow and subarctic terrain, maintained primarily for transport and resource transit rather than permanent settlement.
