Deep within the rugged expanse of the Nahanni Valley, a string of unexplained disappearances and grisly decapitations earned the region the ominous nickname “Valley of the Headless Men.” Between about 1905 and 1945, at least four bodies were found severed from the neck, sometimes in burned camps, and many others vanished without a trace. The heads of the discovered victims were never recovered, and no one has ever been held responsible. The remote wilderness, gold-seeking expeditions, bitter rivalries, and supernatural legends swirl together in a mystery that continues to defy explanation.
