Scientists Discovered A Ticking Time Bomb Throughout Alaska’s Underground

That red shack is not a freezer. It is a tunnel 40 feet below the ground, called the Cold Regions Research and Engineering Laboratory (CRREL). Since the 1960s, scientists have studied the Alaskan terrain there.

CRREL labs exist across the U.S., studying everything from water conservation to military engineering. But in Alaska, scientists made a disturbing discovery.
