There are many unexplainable phenomenons in this world, but one of my favorites are ice circles. For some reason these beautiful shapes appear on frozen water that flows slowly. Because of the flowing water, these huge circles also rotate slowly on the surface of the water. That's why many UFO-enthusiasts claim that ice circles are actually signs left by visiting aliens, just like crop circles.

Ice circles normally occur at bends in the river where the accelerating water creates a force called 'rotational shear', which breaks off a chunk of ice and twists it around. As the disc rotates, it grinds against surrounding ice and the result is a perfect circle that people call "Ice Circle". Ice circles have most frequently been observed in Scandinavia and North America, but was also recorded in Britain and Russia.
