2018 Map of Demarcation Point C-5 SW

About this map

The Okpilak River dominates the western landscape of this North Slope region, carved by Arctic drainage patterns that define the northern coastal plain. This 2018 survey by the U.S. Geological Survey details a landscape shaped by dynamic hydrology, where Okpilak Cr and the wider Jago River to the east create a complex network of braided channels and wetlands. The map highlights the vastness of the North Slope borough, illustrating the absence of permanent infrastructure or settlements in this remote territory. Instead, the focus remains on the natural boundaries and township lines, including t3n r33e and t2n r34e, which provide the only human-imposed structure on an otherwise wild terrain of the Alaskan Arctic.
