Mountain of the Dead: The Dyatlov Pass Incident
One of the most bizarre, not to mention flat out terrifying, mysteries of the modern age concerns the enigmatic deaths of nine Russian mountaineers whose cross-country skiing trip ended in a tragedy so ghastly and perplexing that it has mystified experts for over half a century. Excursions into nature can be serene for some and exhilarating for others, but for an unfortunate few these sojourns into the untouched wilds of our world can be tragic. Still other such journeys into the unknown end in such unfathomably frightening circumstances that they become the stuff of legend. The proof of this tragedy exists not only in the plethora of photographs that have been preserved, but also in the extensive records (many of which are still allegedly classified) of the Soviet military who investigated the odd case and were manifestly unable to reach any definitive conclusions despite an overwhelming amount of physical evidence. The date was January 28, 1959.
