There's a 'Doorway to The Underworld' in Siberia So Big It's Uncovered Ancient Forests



A doorway to 200,000 years ago.

It's no secret that Siberia's permafrost is on thin ice. Conditions are varying so much that huge holes are appearing out of nowhere, and, in some places, tundra is quite literally bubbling underneath people's feet.

But one of the biggest craters in the region, known by the local Yakutian people as the 'doorway to the underworld', is growing so rapidly that it's uncovering long-buried forests, carcasses, and up to 200,000 years of historical climate records.

The instability of the region isn't just dangerous for locals, there are also concerns that as the hole gets deeper and larger, it will expose carbon stores that have been locked away for thousands of years.

That's in addition to the preserved remains of long-buried forests, ancient pollen samples, and even the frozen remains of a musk ox, mammoth, and a 4,400-year-old horse. -
