An ideal ice circle has formed on the Narym River in eastern Kazakhstan. A resident of Ulken Naryn village filmed the natural phenomenon on his cellphone while fishing, reports Altaynews.kz.
The author of the video believes that the ideal circle is a result of a vortex that shaped the ice into this ideal form.
Some internet folks with wild imagination suggested that the ideal circle is a sign left by aliens.
