The Trans Alaska Pipeline System, called "The Pipeline" by Alaskans, is one of the greatest engineering projects of the world.
In 1968, oil was discovered on the North Slope of Alaska. The only way to carry this oil from the North Slope of Alaska was by a pipeline over land. In the 1970s the 800 mile-long Pipeline was constructed to move oil from Prudhoe Bay on the Arctic Ocean (start point) to the port of Valdez (end point). Valdez is the northernmost ice-free port in North America.
