The ice circle appeared in SiberiaBaikal Lake. Scientists have denied the involvement of UFOs, and assuming that warm water has been blown up into a circular shape from the bottom of the lake, it is said that the source of warm water has not been found and is confused about. Furthermore, similar ice clubs have been found in other parts of Lake Baikal, and it seems that more and more I do not know why the ice circle was made.
