Second mysterious crater reported from Yamal
Last week, Russian scientists estimated the first hole, which has smooth sides and a lake at its bottom, to be around 30-60 meters wide (100-200 feet) wide. The second crater is said to be smaller than the first, only about 15 meters (50 feet) wide, and it’s reported to be filled with snow.
Both craters (assuming two exist) are located within the permafrost of the Yamalo-Nenets Autonomous Area (YNAO) of the Russian Arctic. Moscow Times said that both craters appear to have formed relatively recently.
In fact, according to the website Russia Behind the Headlines, the time of formation of the second crater might be known, from reports last year by reindeer herders. This website said the second crater might have formed in September 2013.
