Alaska Pipeline: Atigun Pass
Video duration: 1:19
In the winter of 1976, Alaska Pipeline construction workers faced the daunting task of laying pipe at Atigun Pass, the highest point on the line rising at 4,800 feet above sea level. Additionally, the arctic weather made for extremely difficult working conditions. Due to the threat of avalanches at Atigun Pass, the pipe had to be buried beneath the permafrost soil.
