2024 Map of Demarcation Point A-4 SW

About this map

Aichilik River meanders across this high-latitude terrain, carving through the Brooks Range foothills in the northernmost reaches of the state. This landscape is defined by its status as protected wilderness, falling entirely within the Arctic National Wildlife Refuge and the Mollie Beattie Wilderness. The map reveals a complex drainage network where countless unnamed seasonal streams and tributaries feed into the main river channel, illustrating the hydrologic patterns of the North Slope. Surveyed with modern precision, the topography shows the steep relief of the mountains giving way to the tundra, documenting a region where the natural environment remains largely unaltered by infrastructure or permanent settlement.
