Planet Baikal (2013)
Планета Байкал
For several years, scientists studying images of our planet from space have been talking about an unusual phenomenon that periodically appears on the surface of the deepest lake in the world, at Baikal. Every year, when the lake is covered with ice, huge concentric circles of regular shape appear on it. They are not visible from the earth, but from space these huge geometric figures are clearly visible.
