2018 Map of Demarcation Point D-4 SW

About this map

Braided river systems and expansive arctic wetlands dominate this high-latitude terrain within the Okpilak River drainage. The landscape is defined by the shifting paths of the Ikerukvik River and Niguanak River, which meander through a complex mosaic of ponds and marshland characteristic of the North Slope. Surveyed at a scale of 1:25,000, the data reveals the intricate hydrography of the coastal plain, where seasonal changes and permafrost influence the flow of these northern waterways. This 2018 edition provides a precise look at the township and range divisions, including t6n r35e and t5n r36e, in a region where natural features serve as the primary landmarks.
