2018 Map of Demarcation Point A-5 SE

About this map

The Jago River provides the central geographic feature of this 2018 survey within the North Slope Borough, cutting through high-latitude terrain defined by glacial influence and steep elevation changes. This specific area, charted between the 69th and 69.125th parallels, is divided by the Public Land Survey System boundaries of t4s r35e, t4s r36e, t5s r35e, t5s r36e, and t5s r37e. The map represents a contemporary look at a landscape where traditional human settlement is absent, focusing instead on the hydrological patterns of the river system as it flows northward toward the Arctic coast. Modern topographic data reveals the complex drainage basins and glacial cirques that characterize this remote portion of the Brooks Range foothills.
