the forest holes of russia
People have been finding strange holes in Russian forests. This has been occurring since the end of the 1980s. This strange phenomenon consists of deep holes that appear suddenly in the dense forests, in those places that no truck or car can get to, let alone drill anything. If these holes are being dug, there is no soil around these holes that indicate that they have been drilled. People who have gone down these holes haven’t found anything, and there is no answer on how these holes are made.
