2015 Map of De Long Mountains B-1 NE

About this map

The Noatak National Preserve encompasses the majority of this landscape in the De Long Mountains, protecting a complex watershed where the Kelly River winds through the northern reaches of the Iluyak Basin. The terrain is defined by the prominent Avgun Hills, which rise above the river valley in a region characterized by its lack of permanent infrastructure or settlements. This survey by the U.S. Geological Survey provides a precise look at the drainage patterns and elevation changes across the Arctic tundra, serving as a critical record of the North Slope's protected wilderness. The drainage network of the Kelly River and its unnamed tributaries illustrate the hydrological character of the basin as it sits within the administrative boundaries of t11s r44w and t12s r44w.
