2016 Map of Survey Pass D-5 NE

About this map

The Continental Divide defines the hydrologic character of this remote Alaskan interior landscape, where the waters of the Nigu River flow northward while the Alatna River drains to the south. This 2016 survey documents the high-altitude headwaters within Gates of the Arctic National Park, a vast wilderness designated for its ecological and scientific value. The map illustrates a landscape shaped by glacial action, showing the intricate contour intervals of the surrounding peaks and the braided paths of these primary river systems as they move through the Brooks Range. The absence of roads or established settlements emphasizes the character of this protected wilderness area, serving as a baseline for the geographic features and water systems at the heart of the park.
