2017 Map of Philip Smith Mountains A-5 SE
USGS Topo · Published 2017About this map
The Alaska Pipeline and Dalton Highway serve as the primary human corridor through this high-latitude terrain within the North Slope Borough. This infrastructure follows the narrow valley floor, flanked by steep mountain contours, providing the only overland link through this Arctic interior. The small outpost at Chandalar Shelf and the adjacent Chandalar Shelf Airport mark a critical logistical point in the Brooks Range foothills. The landscape is defined by the drainage systems of the Dietrich River flowing south and the Atigun River in the northern portion of the quadrangle. This 2017 survey shows the precise alignment of the pipeline and road as they navigate the varying elevations, illustrating the engineering required to maintain this vital energy and transport artery in a geography characterized by extreme relief and glacial watercourses.
