FAIRBANKS, Alaska (KTVF) - Ice wedges, pre-historic animal bones, and frozen plant matter line the walls of a hole dug straight into the side of a hill near Fairbanks. The U.S. Army Corps of Engineers Permafrost Tunnel was first built in the Goldstream Valley in 1963 to see how well permafrost could act as a bunker during the Cold War. By the next year, it was turned over to the Cold Regions Research Engineering Laboratory (CRREL). Originally built 100 meters deep, the tunnel's size tripled with an expansion project, starting in 2011.
