Trans Alaska Oil Pipeline

The Alaskan pipeline was constructed both above-ground and below-ground.  In unstable areas like the permafrost in Alaska, where the ground can thaw, the pipeline is above ground and insulated with fiberglass to keep the heat from the oil away from the ground.

The Trans Alaska Pipeline is 800 miles long, it took 3 years to finish and when it was first completed, the pipes expanded 4 feet per mile because of the temperatures.  This is the reason for the zig-zag shape of the pipeline.

 There's the pipe in the trees!

 Huh?

 Oh!!!

 This is how high the pipeline is above the ground in some parts.

 This is where the pipeline goes in Alaska, north to south.

 Someone's yard decoration across from the pipeline.
