Dyatlov pass incident
Was in russia in 1959.Nine hikers were go to hike a mountain .which was called dead mountain. The mountain was in Siberia. There was a snow storm and they put up their tents. They telegraphed their friends to tell them not to worry they might be comig late. On feburary 20, the friends got worried and they sent a search party. Then they found their tent with a knife mark from the inside. Some of their clothes was still inside the tent. A couple of miles away they found the hikers. Two were frozen because they only had underwear. The others were stacked on top of eachother.
