About this map

The Colville River dominates this portion of the Arctic coastal plain, carving a complex network of braids and distributaries through the North Slope landscape. This 2017 survey documents the hydraulic intricacies of the delta region, where the Tamayayak Channel and Elaktoveach Channel divert from the main riverbed. The terrain is characterized by extensive wetlands and seasonal water bodies typical of this permafrost-underlain environment.

Prominent landmarks such as Kachemach Mound and Anajuk Point provide rare elevation in an otherwise flat expanse. To the east, the Kachemach River and Sakoonang Channel further define the drainage patterns of this remote coastal sector. The map serves as a precise record of these shifting arctic waterways and the fragile tundra environment before the onset of further shoreline or hydrological changes.
