2016 Map of Survey Pass C-3 SE

About this map

The Endicott Mountains dominate the northern landscape of this interior wilderness, located within the protected boundary of Gates of the Arctic National Park. This survey captures a remote subarctic environment defined by the confluence of major glacial drainage systems. The Unakserak River flows southward through a wide glacial valley to join the Alatna River, a significant waterway that meanders through the central portion of the map. These rivers, along with the tributary Aulinyak Creek, represent the primary travel corridors in a region devoid of roads or permanent settlements. The topographic detail reveals the complex hydrology of the valley floors, where the rivers split into braided channels and seasonal wetlands, illustrating the shifting nature of these arctic watercourses before they reach the Koyukuk River basin.
