2024 Map of Barter Island A-4 SW

About this map

Arctic National Wildlife Refuge encompasses this entire stretch of the Alaskan North Slope, where the intricate hydrology of the coastal plain meets the Beaufort Sea. The landscape is dominated by the braided reaches of the Jago River, which flows northward through expansive wetlands before emptying into the protected waters of Jago Lagoon. This area represents a critical intersection of terrestrial and marine environments, featuring a complex network of thaw lakes and coastal features like Martin Point and the eastern reaches of Tapkaurak Lagoon. The map illustrates the specialized geography of the Arctic coast, where seasonal river discharge and sea ice dynamics constantly reshape the barrier islands and lagoon systems that define this remote wilderness.
