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.
Some Finnish folklore explains the odd locations of these giant stones by saying that trolls or giants carried, threw or rolled them there.
Actually, the rock was left in that position by a glacier during the last Ice Age. This rock and others like it are known as “glacial erratics”. It’s easy to see the glacial striations still in evidence underneath the rock (glacial striation refers to the marks left by glaciers moving over a hard surface).
