2016 Map of Survey Pass A-3 NW

About this map

Walker Lake dominates the southern landscape of this high-latitude survey, its deep waters framed by the steep topographic contours of the Brooks Range. The map captures a significant administrative boundary where the Northwest Arctic Borough meets the Yukon-Koyukuk Census Area, a line that runs through the interior of Gates of the Arctic National Park. The terrain is characterized by massive elevation changes, represented by dense contour lines that define the ridges and valleys surrounding the lake basin. This area remains largely defined by its natural topography rather than human infrastructure, reflecting the protected status of the national park. The cartography provides a clear view of the drainage patterns and peaks within townships t21n r20e and t21n r21e, showing the land as it appeared in the mid-2010s.
