About this map

The Continental Divide winds through this Brooks Range landscape, marking a profound hydrologic boundary between the Arctic and Pacific drainages. Flowing northward toward the Arctic Ocean, the Anaktuvuk River and Nanushuk River dominate the northern slopes, while the headwaters of the North Fork Koyukuk River drain south toward the Yukon River system. This high-altitude terrain is defined by the remnants of glacial activity, visible in the West Alapah Glacier and East Alapah Glacier which cling to the heights of Alapah Mountain.

Transport through this wilderness is dictated by natural corridors like Ernie Pass, providing a crossing point between the Anaktuvuk and the Valley of Precipices Creek. The naming conventions found on the map, such as Marshmallow Mountain, Cockedhat Mountain, and Rumbling Mountain, reflect the descriptive character given to these landforms by early 20th-century surveyors and local travelers. The map captures the area as it was recorded in the early 1970s, showcasing a landscape shaped by ice and water.
