1955 Map of Demarcation Point C-5

USGS Topo · Published 1976

About this map

The Arctic National Wildlife Range dominates this mid-century landscape on the North Slope, where the terrain transitions from braided river valleys to the rising foothills of the interior. The survey captures a vast, roadless expanse defined entirely by its drainage systems, most notably the wide, shifting channels of the Okpilak River and the Jago River. These glacial waterways, fed by smaller tributaries like Akubiktak River and Igilatvik Creek, illustrate the complex hydrology of the Arctic coastal plain before any significant human infrastructure was established in this quadrant. Mapped from 1955 aerial photography, the sheet records the natural state of these watersheds, including the winding course of Okpirourak Creek as it carves through the unsurveyed and unmarked lands of this northern wilderness.
