2017 Map of Tanana D-1 NE

About this map

The Alaska Pipeline cuts a distinct industrial line across this remote section of the Yukon-Koyukuk region, providing a sharp contrast to the wandering drainages of the Ray River and the Big Salt River. This 2017 survey documents a landscape defined by the intersection of critical energy infrastructure and a complex hydrological network. The terrain is marked by the winding course of the Ray River as it moves through the northeastern quadrant, while the Big Salt River establishes the southern boundary of the map. The spatial relationship between the pipeline corridor and these waterways highlights the engineering considerations required to traverse this interior Alaskan environment during the early 21st century.
