The Batagaika Crater is not a crater at all, but a depression in northern Russia. It is being caused by the thawing of permafrost, and depressions like this are occurring all over the north. Batagaika is by far the largest depression. Its erosion has been documented by satellites, and now appears to have doubled in area since 1999. While depressions like this are a result of climate change, they also allow scientists to easily study things that were once buried.
