2018 Map of Demarcation Point D-5 NW

About this map

The Okpilak River dominates this Arctic landscape, its braided channels carving a path through the North Slope toward the Beaufort Sea. In this 2018 survey, the river is the central geographical feature, meandering through a vast expanse of coastal plain and wetlands. The map provides a detailed look at the hydrology of the region as it appeared in the early 21st century, showing the complex network of minor tributaries and seasonal water bodies that define the terrain. These water patterns reflect the unique drainage characteristics of the Arctic tundra, where the landscape is constantly reshaped by seasonal flows and permafrost conditions.
