1971 Map of Chandalar D-6

About this map

The Trans-Alaska Pipeline is the industrial centerpiece of this 1970s survey, carved through the valley of the Dietrich River. Published during a pivotal era of Alaskan infrastructure development, the map documents the corridor of the pipeline as it began to reshape the Brooks Range landscape. The terrain is anchored by massive formations like Table Mountain in the north and Snowden Mountain to the south, with the North Slope Borough boundary cutting across the high ridges. Complex water systems feed into the main valley, including Kuyuktuvuk Creek and Nutirwik Creek. This edition is particularly valuable for its purple photorevisions, which capture the physical imprint of the pipeline construction efforts as they appeared mid-decade, providing a precise spatial record of one of the 20th century's most significant engineering feats.
