1955 Map of De Long Mountains

About this map

Noatak National Monument occupies the southeastern corner of this map, reflecting a time of significant federal land conservation in the Arctic. The landscape is defined by the De Long Mountains and the intricate drainage basins of the Kukpowruk River, Wulik River, and Kokolik River. Resource exploration is evident along the coast of the Chukchi Sea, where Thetis Mine and a Drill Hole near Poko Mountain signal industrial interest in this remote area during the mid-20th century.
