An excerpt from the article 39 facts about Dyatlov Pass incident

On February 26, 1959, the tourists' tent was found with the participants' jackets and footwear inside. This is incomprehensible because, according to various sources, the temperature that night could have been well below -20 degrees Celsius. In addition, the tent had many cuts made with sharp objects (most likely a knife) about 3 centimeters in diameter, as well as two larger cuts. Each of the cuts was made on the inner surface of the tent.
