About this map

The Chandler River carves a significant course through this North Slope landscape, creating the prominent Big Bend as it flows toward the Arctic. Photogrammetric methods from 1955 captured a wilderness primarily defined by its hydrology and relief, from the Nakaktuk Lakes in the northwest to the elevated points of Natvatchiak Hill and Paunagaktuk Bluff.

Evidence of seasonal travel is preserved in the form of a Winter Trail that traverses the northern and southern sections, indicating established routes used when the tundra was frozen. The area is characterized by the Kulehik River and numerous unnamed drainages, reflecting an era of surveying where land lines remained unsurveyed and predetermined by the Bureau of Land Management. This sheet serves as a primary record of the terrain before later developments in the region.
