OK, this hole definitely needs to be looked into. A third mysterious crater has been found in Siberia. This one was discovered in the Taymyr Peninsula by local reindeer herders who live in the northern village of Nosok.

The area is east of Yamal, where the first crater was reported last week, and northeast of the Taz district where the second one was found. This hole is smaller than those two – about 4 feet in diameter – and observers say its perimeter is perfectly round and the 100-to-300-feet-deep hole is shaped like a cone. According to The Siberian Times, one described it this way:

It is not like this is the work of men, but also doesn’t look like natural formation.

News travels slowly in Siberia. Local residents say the hole was formed on September 27, 2013. Shortly after, Mikhail Lapsui, a deputy of the regional parliament, flew over the area by helicopter and gave this account:

“There is ground outside, as if it was thrown as a result of an underground explosion. Observers give several versions. According to the first, initially at the place was smoking, and then there was a bright flash. In the second version, a celestial body fell there.”

Geologists, ecologists and historians are unable to come to a consensus on the causes of the craters. The prevailing theory on the other two is methane gas releases caused by global warming melting the permafrost. However, the Taymyr crater is far from the gas fields of the Yamal and Taz areas and is smaller, cone-shaped and perfectly formed.

Could it have another cause? Marina Leibman, chief scientist of the Earth Cryosphere Institute, says more information is needed.

Undoubtedly, we need to study all such formations. It is necessary to be able to predict their occurrence.”

Especially if it “doesn’t look like natural formation.”
