Few events in modern history have inspired as many competing explanations as the Dyatlov Pass incident. For more than six decades, researchers, journalists, scientists, and amateur investigators have tried to answer the same haunting question: why did nine experienced mountaineers leave the safety of their tent in the middle of a freezing winter night, wearing little or no clothing, descend a mountain in temperatures approaching –30°C (–22°F), and ultimately lose their lives?

Snow blanketed the northern Ural Mountains that night, just as it had for thousands of years before. Relentless winds swept across the barren slopes, carrying curtains of ice through a landscape where temperatures had plunged far below freezing.
