Russian scientists are about to unravel the mystery of several giant holes in the permafrost of the Yamal Peninsula. The ‘Black holes’ began to appear in the ground around 2013, baffling both the local Nenets population of reindeer herders, and visiting scientists.

At last, they might have come close to explaining the mystery of the Yamal craters.
