There are thousands of thaw slumps across the Arctic. But the size of the Batagay "crater" has earned it the title of megaslump. It's named for the nearby town of Batagay.
"Permafrost is not the most, let's say, photogenic of subjects," Roger Michaelides, a geophysicist at Washington University in St. Louis, told Business Insider. "You're talking mostly about frozen dirt underground, which by definition you often can't see unless it's been exposed somehow, like in this megaslump."
