2017 Map of Philip Smith Mountains A-5 NE

About this map

Atigun Pass and the high peaks of the Brooks Range dominate this modern survey of the North Slope. The landscape is defined by the vital transportation corridor carved through the mountains, where the Dalton Highway and the Alaska Pipeline run parallel to the Atigun River. This represents a critical point in Arctic infrastructure, showing the engineering required to traverse the continental divide at one of Alaska's most significant mountain passes. To the west of the river valley, James Dalton Mtn rises as a prominent landmark, overlooking the complex series of glacial valleys and drainage systems that characterize the region. The map provides precise detail on the elevation changes and hydrology around the headwaters of the river, documenting the intersection of industry and extreme terrain in the early 21st century.
