The Dyatlov Pass Incident is a notorious case involving the deaths of nine hikers in 1959, while in the Ural mountains of Russia. Because every member of the group died, and there were no other eye witnesses, there have been a number of speculative theories regarding the mysterious deaths. From the evidence at the scene, it appeared that the hikers had cut open their tents from the inside, and fled into the wilderness in just their socks or bare feet. One of the hikers had major skull damage, while a couple more had multiple chest fractures. Despite this, none of the corpses had any signs of a struggle. A few of the corpses had their tongues and eyes missing, though this was likely due to them being easy food for local wildlife. The official explanation for the deaths was a "compelling natural force", but the case was embroiled in controversy, with several parties citing that the deaths were linked to secret weapons tests. Evidence for this theory included the hikers' radioactive clothing, scrap metal found scattered nearby and another group of hikers nearby seeing bizarre orange spheres in the sky on the night of the deaths.
