After watching the last of the caribou descend into the valley shelf to join their family members on the other side of the road, we continued toward Galbraith by ascending a long, steep, uphill winding road to the summit of Atigun Pass. The pipeline remained to our right in a buried, insulated concrete cribbing to protect it from rock slides and avalanches, and to keep the ground from thawing. Imagine constructing the pipeline in such conditions!
