what is 'Dyatlov disappearance Incident'? 

On February 2, 1952, a Russian expedition consisting of seven men and two women was discovered in the Ural Mountains as suspicious bodies.

The case was named after Dyatlov, the captain of the expedition.

On January 28, 1959, Dyatlov and nine explorers prepared to explore the northern Ural Mountains.

However, one of the crew on the day of the expedition was excluded due to fever and headache, and nine of them left the expedition.

They were very skilled skiers and experienced explorers at the same time.

Five days after the start of the expedition, heavy snowfalls broke out, and the crew, who remained in base camp, sent a probe to the exploration team in anxious minds.

Dyatlov reported that they set up temporary camps and then rested there.

However, the next day, they were suddenly lost contact, and they did not come back on February 12, the expected end date of the expedition

Then they sent out a search team to find their camp.

However, clothes, ski equipment, and exploration tools were left as is, and the tent was badly damaged.

One strange thing is that the tent is torn from the inside, not from the outside.

The search team found 5 bodies at 1.5KM away from the camp. and five of them were found without a clothes, and their face was a panic expression.

Why did they come out hastily without clothes?

The search for the remaining 4 people continued, and on May 4, two months later, the rest of the body was found in the nearby valley, but it was disastrous.

One had skull, the other had broken ribs, and one of the female members had their tongue cut cleanly. and No traces of rebellion could be found by a female member whose tongue was cut off.

The commonalities found in their bodies were that the skin was discolored in orange, and in their underwear a significantly high radioactivity was detected.

Various speculation of the case

01. Incident caused by hallucination of poisoning

There was a lot of Poison plants growing around the tent.

They claimed that they used the Poison plants to smoke a bonfire and fell into the hallucination of the poison. 

However, no substance was found to cause hallucination in the Poison plants.

02.  A sudden escape from an avalanche

they claimed to have escaped the tent quickly because of the avalanche, but The place where the camp is located was flat, so there was no possibility of an avalanche.

There have been various speculations since then, but there is no truth.
