A strange phenomena is happening in some Russian forests. People are finding strange, deep holes.
They appear in the dense forest, in the places you can’t get on the car or truck to bring any device to drill the ground. There is no soil nearby that should be taken from such deep hole.
When people are brave enough to venture into the holes, they find that they end abruptly in the darkness. There are no any reasonable ideas on how these holes appear and what they are being used for. No one knows who or what is digging these holes or why.
There are about 10 holes in the field. Each hole has an entrance to a cave-like hollow place in the earth. Some of the tunnels are big enough for a person of medium height to stand up straight. According to one of the suppositions, all the underground passages are interconnected in a network. A few daredevils equipped with flashlights attempted walking across the tunnels.
