1955 Map of De Long Mountains A-2

About this map

Noatak National Monument occupies the eastern portion of this landscape, reflecting a remote wilderness before its formal designation and later revisions. The topography is defined by the drainage of the Wulik River, which snakes through the northwestern sections, fed by tributaries like Ikalukrok Creek. The terrain is punctuated by significant high points including Punupkahkroak Mountain and the central Deadlock Mountain. These landforms dictate the passage of water through the region, where Wrench Creek flows in the far northeast corner. The map also records the North Slope Borough line, marking a political division in an area otherwise characterized by its topographical isolation and lack of developed roads or settlements in the mid-20th century.
