2017 Map of Wiseman A-1 SW

About this map

The Alaska Pipeline and the adjacent Dalton Highway dominate the north-south axis of this sub-Arctic landscape, cutting a modern industrial corridor through the wilderness. These engineering feats parallel the natural drainage of the Middle Fork Koyukuk River and its various tributaries. The map shows the intricate wetland patterns and shifting hydrology of the region, evidenced by features such as Chapman Island and the meandering Chapman Cr. In the northern portion of the quadrangle, the Windy Arm feeds into the larger river system, while the southern reaches are defined by the presence of the South Fork Koyukuk River. This document captures the stark contrast between the remote, uninhabited terrain of the Yukon-Koyukuk region and the critical energy infrastructure that traverses it.
