An RT documentary team travelled to the Yamal peninsula on Saturday to look inside the largest of a series of giant mystery sinkholes, the Yamal B-1 crater, which was discovered in Siberia about a year ago. The 60-meter-deep and over 500-meter-wide crater was discovered by helicopter pilots, about 30 kilometers from Bovanenkovo in the Yamalo-Nenets region of Siberia. Aside from the B-1 crater, two other giant craters have also been discovered in Russia. There is still no clear explanation for the perfectly round shape of the holes as well as the appearance of dozens of smaller craters around the mother holes.
