The "Alaska Triangle" is a rugged region connecting Anchorage, Juneau, and Utqiagvik where over 20,000 people and numerous aircraft have vanished since the 1970s. The area gained notoriety after the unexplained 1972 disappearance of Congressmen Hale Boggs and Nick Begich. While theories for the vanishings include energy vortexes, aliens, and the shape-shifting Kushtaka demon, experts primarily blame the region's harsh weather and perilous geography.
