Mysterious cauldrons at the Vilyuy valley

By the legends of local hunters there are some mysterious cauldrons at the valley of river Vilyuy (Yakutia). You can go down them by the entrance on the top part and go downstairs under the ground where are several rooms. Even when the temperature outside is 30° below zero, inside the cauldron is warm and cozy. Therefore, many hunters are tempted to go inside, but if they spend too much time there, they die of a mysterious disease, that is why the name of the valley is the Valley of Death and the local authorities have stopped hunters from going there. Cauldrons are supposed to be manufactured of an unknown reddish metal, which is unbelievably hard that hunters could not even scratch it with their own knife.

Expedition of Ivan Mackerle

There was an expedition of the Czech mysticist Ivan Mackerle in 2006, who discovered three of these cauldrons. Unfortunately, the three were buried under the surface of the swamp and without any equipment it was impossible to uncover the entrance to take the sample of the metal. Moreover, Ivan Mackerle displayed the symptoms of the mysterious disease, which involved vomiting, loss of balance, loss of consciousness and chills. Therefore, they decided to end the expedition prematurely and transport him to the hospital.

Ivan Mackerle died in 2013, 7 years after the expedition to Yakutia. Therefore we decided to follow in his footsteps in order to continue in his research of this mystery.

Objectives of our expedition

Our aim is to explore one of these cauldrons, measure as many physical quantities as possible (temperature, radiation, magnetic field, composition of gases in the air) and get a sample of the unknown metal. In addition, we also plan to film a documentary throughout the whole expedition.

We are very serious in this expedition and would like to have many scientists and experts in the field. Hopefully, this can reach out to the wider world via articles in magazines or perhaps even on the Discovery Channel.

Four theories

There are four theories about these Cauldrons:

  1. There is nothing there whatsoever.
  2. An unknown geological phenomenon.
  3. It was built by a former human civilization.
  4. It was built by an extraterrestrial civilization.

The first theory is disproven, as shown by Ivan Mackerle and the fact that local hunters were dying in the area. In that case, the remaining three theories are down to us, regardless of which theory it is, discovering the truth will be a huge success.

If you want to help us somehow, you can donate to our cause through our crowdfunding campaign at Nakopni.Me. We would appreciate it if you could sponsor such a fascinating expedition.

We are looking for

We quantified the cost of the expedition to 2 300 000 CZK. We are proactively addressing companies and persons, we are looking for sponsors or partners for cooperation. To collect the money we created the crowdfunding campaing at Nakopni.Me, for 20 000 CZK you can buy a lottery ticket and become the member of the expedition.

In the near future we will start to look for the members of the expedition, but you can start applying already. We are looking for people for these roles:

geolog / geofyzik

geologist / geophysicist

The area is full of magnetic anomalies, interesting rocks and minerals. Geologist or geophysicist will enjoy it a lot.

operátor / mechanik

operator / mechanic

We take a lot of toys (drone, water pump, measuring devices, generator, …), we need somebody to operate it and do some minor fix if necessary.



We want to film a documentary movie of the whole expedition, cameraman will guarantee the quality of the source videos. Experience with the underwater filming is a plus.



It is possible that we fail to drain away all the water, in that case we must dive into the water. Experience with the underwater filming is a plus.



As experienced by the previous expedition of Ivan Mackerle it is obvious we could get into some medical troubles, the doctor will be useful in this situation.



The guide will take care of all the members, support them with the food etc. We aim to hire somebody local, but if you persuade us about your experience, you can become our guide.
