The Alaska pipeline starts at the frozen edge of the Arctic Ocean. It stretches southward across the largest and northern most state in the United States, ending at a remote ice-free seaport village nearly 800 miles from where it begins. It is massive in size and extremely operate.
The steel pipe cresses windswept plains and endless miles of delicate tundra that tops the frozen ground. It weaves through crooked canyons, climbs sheer mountains, plunges over rocky crags, makes its way through thick forests, and passes over or under hundreds of rivers and streams. The pipe is 4 feet in diameter, and up to 2 million barrels of crude oil can be pumped through it daily.
Resting on H-shaped steel racks called "bents," long sections of the pipeline follow a zigzag course high above the frozen earth. Other long sections drop out of sight beneath spongy or rocky ground and return to the surface later on. The pattern of the pipeline’s up-and-down route is det
