We are talking about a mysterious cave, the entrance to which is located in the middle of the Khakass highlands, on the slope of Mount Kashkulak. The locals themselves are wary of wandering in those places, and even more so, they never try to get inside the cave, which since ancient times has been called the Black Devil's Cave.
Devil's black cave
Old-timers tell a legend, according to which, in the vicinity of Mount Kashkulak, in ancient times, flowed a sacred river called "Golden Stream". It was believed that it was along this stream that the souls of the dead went to the world of the dead, and the great shaman accompanied them on their last journey.
However, many years passed and one day the time came for the shaman himself to die. People, observing the customs of those times, burned the body, and scattered the ashes over the Golden Stream. According to legend, it was at that moment that these places became the gates to the otherworldly worlds.
Scientists were interested in the Kashkulak anomaly back in the middle of the last century. An entire expedition of archaeologists arrived from Moscow, but the scientists did not manage to start research. An unknown force stood in the way of science.
As soon as they entered the cave, all members of the expedition felt an attack of unmotivated fear, there was no way to stay there, something literally drove people out of the dungeon.

Since then and to this day, many attempts have been made to lift the veil over the mystery of the Kashkulak cave. Anyone who went inside showed incomprehensible symptoms of sudden fear, oppressive discomfort, confusion, and auditory and visual hallucinations.
Thanks to the installed equipment, it turned out that as soon as a person enters through the external entrance, a whole magnetic storm begins in the cave. The researchers came to the unequivocal conclusion that electromagnetic disturbances are of artificial nature, and the source-generator is located somewhere in the thickness of the mountain.
