title: Siberian Fan Reliefs and the Tunguska Cosmic Body
abstract: Unusual reliefs on the Earth’s surface were found in aerial photographs of Eastern Siberia in the late 20th century. The facts justifying the connection are given by Siberian Fan Reliefs and the Tunguska Cosmic Body. It is most natural to assume that we are dealing with the falling of numerous fragments of a collapsed comet. The more likely version is that the comet is captured by the Earth-Moon system and remains in Earth orbit for some time.
