The Great Tunguska Explosion, Russia
(1908)
Alexey Zolotov (1926-1995), Soviet geologist and investigator of the Tunguska explosion of 1908 that devastated a remote region of Siberia. Zolotov was a department head at the All-Union Institute of Geophysical Prospecting Methods. From 1959, he investigated Soviet science fiction writer Alexander Kazantsev's theory that the Tunguska explosion was caused by an alien spacecraft impact and nuclear explosion, rather than by a meteorite or comet. Zolotov published his findings in the 1960s after several state-funded expeditions to the area. Photographed in 1965, in Ufa, in the Republic of Bashkortostan, Russia.
