2017 Map of Philip Smith Mountains A-4 NW
USGS Topo · Published 2017About this map
The Alaska Pipeline corridors along the western edge of this territory in the Brooks Range, marking a significant industrial artery through the North Slope. This landscape is defined by the high-elevation divide between two major arctic drainage systems. To the north, the Atigun River flows toward the Arctic Ocean, while the N Fork Chandalar River winds through the central and southern reaches, eventually contributing to the Yukon River basin. The survey details the high-altitude topography of the Philip Smith Mountains, capturing the complex network of alpine valleys and ridges within the t14s r12e and t15s r13e townships. The map highlights the intersection of modern infrastructure and a vast, roadless wilderness where the only human mark is the critical energy lifeline running north-south.
