The locality, located 200 kilometers from Mirny, along the floodplain of the right tributary of the Vilyui River, is called the Death Valley by the locals
It was through this place that the nomadic trade route of the Evenks passed in the past centuries, therefore, eyewitness accounts have survived that in that place there is a huge copper cauldron, or as it was called, the Iron House. Local hunters sometimes spent the night in its premises, which "kept the summer heat in severe frosts", which did not have the most favorable effect on health - after that people were very sick or died, the newspaper "Yakutia" writes. In the archives of the National Library there is a letter from a certain M. P. Koretsky to the Phenomenon commission, who stated that in three visits - from 1933 to 1949 - he had found “eight such cauldrons in this area, in one of which he found a half of an ideal sphere with a diameter 6 centimeters from an unknown metal that can cut glass like butter."
“In 1971, the testimony of an old Evenk hunter was documented that in the area between the rivers Nyurgun Bootur (Glorious Bogatyr) and Ataradak (a large three-sided iron fort) there is an iron hole in which“thin, black, one-eyed people in iron clothes"
“In October 2000, an old-timer of the city of Mirny, a geologist with 50 years of experience, an experienced hunter Vasily Kupriyanovich Trofimov witnessed a strange phenomenon that scared him half to death.

The trees themselves did not bend, but the frost was completely mowed off them. The object walking in this way was not visible, but he, approaching the winter quarters, blocked the sky so that the stars disappeared. In the morning, Vasily Kupriyanovich discovered a strip clear of snow throughout the forest, as long as the eye could reach.
The expedition of the President of the International Academy of Space Esotericism Mark Milhiker in August 2000 discovered mysterious formations similar to slabs on the ground. The Geiger counter next to them was off scale.
There is a hypothesis according to which an alien base is located in the Yakut Valley of Death, which automatically protects the Earth from cataclysms that threaten to result in an ecological disaster. For example, the Tunguska meteorite, which also left many mysteries. By the way, such manifestations of higher intelligence are described in detail in the Olonkho epic in the form of incessant battles between the heavenly heroes and the villainous giants of the Lower World. Other ufologists and journalists believe that Olguydah is a kind of UFO cemetery. The phenomenon of Yelyu Cherkechekh is included in many encyclopedias of anomalous zones of the planet."
