2016 Map of Lookout Ridge A-3 SW

About this map

Lookout Ridge dominates the central landscape of this North Slope Borough survey, forming a prominent topographical spine across the Alaskan wilderness. Below the ridge's southern slopes, the headwaters and drainages of the Lookout River wind through the northern portion of the quadrangle. This 2016 digital rendering by the U.S. Geological Survey provides precise elevation data for a region defined by its isolation and lack of human infrastructure. The map illustrates a pure permafrost environment, where the land is divided only by township and range lines like t4s r24w and t5s r24w, reflecting the systematic grid-based mapping of the American Arctic.
