The Beaufort Sea coastline meets the northern edge of this remote Arctic landscape, where the Ningagapak Lagoon forms a distinct transition between the marine and terrestrial environments. Further inland, the complex drainage patterns of the Kogotpak River and the Aichilik River dictate the character of the terrain, as these waterways meander through the North Slope. This 2018 survey by the U.S. Geological Survey provides a precise view of the hydrology and boundary markings within townships t6n r39e, t6n r40e, t5n r39e, and t5n r40e, capturing a vast expanse of wetland and tundra typical of this high-latitude region.
