About this map

Isabel Pass serves as a critical corridor through the eastern Alaska Range in this 2016 survey, where modern industrial infrastructure follows the path of early Alaskan transport routes. The Alaska Pipeline and Richardson Highway parallel one another as they navigate the high-altitude divide between the Phelan Creek drainage to the north and the headwaters of the Gulkana River to the south. The landscape is dominated by the northern reaches of Summit Lake, a significant alpine water body that feeds the southward-flowing river system.

Smaller water features like Oxbow Lake and McCallum Creek illustrate the glaciated hydrology of the pass. The intersection of Fielding Lake Road and the highway provides a rare point of access in this high mountain environment. This map captures the precise alignment of the state's most vital energy and transit artery through the boundary between the Southeast Fairbanks and Valdez-Cordova Census Areas.
