The Yamal Peninsula is a stretch of peatland above the Arctic Circle, reaching from northern Siberia into the Kara Sea. It is a land of reindeer permafrost, lakes and rivers. But is it also the site of a UFO crash landing that resulted in a giant sinkhole? Other theories for the phenomenon include a meteorite, collapsing rock and global warming.
According to a July 15, 2014 report by The Mirror, scientists are at a loss to explain the massive sinkhole, and some people are theorizing that it may have been caused by a UFO crashing into the Earth. At 80 meters wide, the hole measures more than 262' feet across. That's more than 84 yards. To put it another way, its width is nearly one-fifth of a mile from gaping edge to gaping edge.
The Russian sinkhole is being called the largest in the country and possibly the largest in the world. Its depth is unknown, but there is speculation that it may be deeper than any previously known sinkhole. It almost certainly qualifies as one of the deepest.
The Siberian Times quoted one expert who credits global warming with the formation of the sinkhole around two years ago: "Global warming, causing an 'alarming' melt in the permafrost, released gas causing an effect like the popping of a Champagne bottle cork, she [Anna Kurchatova from Sub-Arctic Scientific Research Centre] suggests."
Despite talk of a possible UFO crash site, some experts are actively pursuing more terrestrial theories. An expedition is being planned that will include various specialists representing the Centre for the Study of the Artic, the Cryosphere Institute of the Russian Academy of Sciences and the Emergencies Ministry. For now, there is no consensus on what caused the impressive sinkhole, and thus far there is no evidence that a UFO was involved.
