"I've never seen such craters in anywhere on Yamal, where I've been. And I've never heard my colleagues talk of anything similar."
They crater was first discovered by video taken from helicopter posted on a social network that went viral.
While they were able to approach it on foot -- slippery oil and water prevented them from getting close to it.
(SOUNDBITE) SENIOR RESEARCH FELLOW OF CENTER OF ARCTIC STUDIES, ANDREI PLEKHANOV, SAYING (WHILE HOLDING MEASURING TOOL):
