About this map

The National Petroleum Reserve In Alaska defines this expansive landscape of the North Slope, revealing a territory primarily shaped by its hydrologic network and remote surveying markers. The Titaluk River meanders across the northern section of the quadrangle, while the Kigalik River winds through the central portion, carving through the tundra. These waterways served as the primary natural corridors in a region largely devoid of permanent settlements or developed roads.

Evidence of human transit is limited to a singular Tractor Trail in the southwest corner, a vital link for seasonal overland movement across the permafrost. Named topographic points like Thumb, Bar 99, and Kigal provide essential landmarks for navigation in the interior. This 1985 edition, based on earlier aerial photography, captures the area during a period of ongoing federal land management and resource evaluation in the Alaskan arctic.
