About this map

Kobuk Valley National Park occupies the central and southern portions of this topographical study within the Northwest Arctic Borough. The landscape is characterized by significant elevational changes, captured in the mid-2010s using modern digital elevation datasets. The map delineates precise public land survey system boundaries, including t22n r1w and t23n r1w, which define the administrative grid of this protected wilderness area. While largely devoid of named human infrastructure or settlements, the intricate contour lines reveal the complex drainage patterns and ridgelines that define the northern Alaskan interior. This survey serves as a definitive record of the park's physical geography before further environmental shifts, providing a high-resolution view of the terrain within the t21n r1w township and surrounding ranges.
