In January 1959, ten students and staff from the Ural Polytechnical Institute, in Russia set out on a cross country hike. Before leaving they had told their friends they would send word by telegraph, there were few phone lines in the area they were heading, just as soon as they reached Otorten, a mountain well known as a hiking and skiing destination. They figured this would happen no later than February 12. One of their team got sick and had to return home. The other nine kept going only to vanish. When their bodies were found no one could explain what had killed them. Here is what I could find.
