Kobuk Valley National Park occupies the central portion of this survey, where the valley floor transitions into the southern foothills of the Brooks Range. The landscape is defined by the drainage of Nekakte Cr, which flows southward through the heart of the quadrangle. This area represents a critical intersection of protected wilderness, with the northern boundary of the map entering the Noatak National Preserve. The mapping records the intricate topography of the region, emphasizing the drainage patterns and elevation changes across townships t24n r2e and t24n r3e during the early 21st century.
