1971 Map of Philip Smith Mountains D-4

USGS Topo · Published 1977

About this map

The Sagavanirktok River valley is documented here during a pivotal moment in the industrial development of the North Slope. Surveyed in 1971 and revised with 1975 aerial photography, the map highlights The Trans-Alaska Pipeline (Under Construction) as it moves through the Arctic landscape. The presence of a Pumping Station along the pipeline corridor reflects the massive infrastructure required to transport oil from the northern coast to southern ports.
