The rumors range from a methane explosion to a UFO landing, but one thing is certain: this sinkhole is huge.
An enormous crater appeared suddenly in part of Russia, a place whose name curiously enough translates as 'the end of the world.' There is not an explanation as to what caused the 262 foot wide sinkhole to appear in the Yamal Peninsula in Siberia.
One Russian expert says the cause is likely to be global warming, releasing gases under the surface, which then explode like a champagne cork. Experts say that the darkening around the inner rim of the crater indicates 'severe burning' which scorched its edges.
