2018 Map of Demarcation Point A-4 SW

About this map

Aichilik River serves as the primary drainage through this high-latitude terrain within the North Slope Borough. This specific area is defined by a rigorous grid of the Public Land Survey System, covering portions of t4s r36e, t4s r37e, t5s r37e, and t5s r38e. The landscape is characterized by extreme relief, where the river braids through a narrow valley floor between steep mountain slopes. The lack of named settlements or infrastructure reflects the isolation of the Arctic wilderness, where the hydrology of the Aichilik River remains the most prominent geographic identifier for navigation and study.
