The Trans-Alaska pipeline carries crude oil from Prudhoe Bay, above the Arctic Circle, south to the port of Valdez on Prince William Sound. The 800-mile route crosses three major mountain ranges, permafrost and earthquake-prone zones, and hundreds of rivers and streams.
During construction, thousands of workers transformed Fairbanks, near the route's mid-point, from a sleepy outpost into a booming frontier town.
