Sixty two years ago an intrepid group of young men and women were determined to hike and ski  through a mountain range in Russia. After they failed to return home rescuers were sent to find them.  What they found stumped everyone. They had all died, some from hypothermia, Some were severely injured, but they wore no shoes and were nearly a mile from their tent.  What happened to these young, healthy, experienced people.  This is one of Russia’s greatest mysteries.  This is the story of the  Dyatlov pass incident.
