About this map

The Trans-Alaska Pipeline emerges as a defining feature of this North Slope landscape, shown here during its 1970s development. The purple revisions on this sheet specifically track the progress of The Trans-Alaska Pipeline (Under Construction) as it moves toward the Atigun River and south into the mountains. This infrastructure arrival transforms a region previously defined by remote waterways and traditional routes like the Winter Trail.
