There are certain natural occurrences and organic structures in the world that leave us all scratching our heads. One such natural wonder is Kummakivi, a geological formation found in the dense forests of Finland. The mystifying sight is that of a giant rock performing an unbelievable balancing act on a seemingly smooth, curved mound. There is still no scientific explanation for how the rock, whose given name translates as "strange rock" in Finnish, has wound up in such a perplexing position, but doesn't it look amazing?
