2018 Map of Demarcation Point D-2 SW

USGS Topo · Published 2018

About this map

Beaufort Sea waters meet the North Slope coastline here, creating a complex system of barrier islands and tidal openings. This environment is characterized by large coastal bodies such as Beaufort Lagoon and Nuvagapak Lagoon, which are sheltered from the open sea by narrow land strips. The hydrological network is dominated by the Aichilik River and the Egaksrak River, both of which drain into the expansive Egaksrak Lagoon. These freshwater inputs through the tundra landscape meet the sea at points like Egaksrak Entrance and Siku Entrance. The map illustrates the intricate wetlands and drainage patterns typical of the Alaska North Slope Borough, including smaller tributaries like Kalokut Cr.
