Atigun Pass Summit — Brooks Range Continental Divide Arctic Viewpoint

Atigun Pass is the single most dramatic point on the entire Dalton Highway run. You’re threading through a narrow glacially carved gap in the Brooks Range at about 4,800 feet — the highest point on any Alaska highway — with near-vertical valley walls pressing in on both sides. In summer the tundra goes electric green, the snowfields linger on the peaks, and Dall sheep work the scree above you. In fall it goes amber and rust. Winter means avalanche closures. This is where the continental divide sits, where the rivers north drain to the Arctic Ocean, and where the climate shifts hard.

The road surface through the pass itself is paved in spots but transitions to rough gravel and can be washboarded and potholed depending on maintenance cycle. No shoulders, no guardrails on much of it. Slow down — trucks run this 24/7 and the sight lines are short. No camping directly at the pass. This is a stop-and-stare waypoint, not an overnight. Avalanche control is active in winter; road closures happen fast. Check AKDOT road conditions before you commit to a crossing window.
