About this map

The National Petroleum Reserve In Alaska dominates this 1980s landscape on the North Slope, revealing a complex network of arctic waterways and tundra wetlands. The Usuktuk River and Topagoruk River meander through the northern reaches, while Ishuktak Creek drains the eastern portion of the quadrangle. These river systems are characterized by extreme sinuosity, reflecting the flat, permafrost-underlain terrain typical of the region.

Evidence of human presence is sparse but distinct, marked by a Tractor Trail cutting through the northeastern sector and the named location of Omalik near the central-east border. This survey, based on 1971 aerial photography, captures the vast, undeveloped character of the Alaskan interior prior to later industrial shifts. The abundance of unnamed lakes and marshy depressions highlights the seasonally saturated nature of this sub-arctic environment.
