Authentic Tunguska Wood for Sale
The specimens in this display are from the "Tunguska Event," which happened June 30, 1908. On that date "something" exploded 8 km above the Tunguska river. About 2,150 square kilometers of Siberian taiga were devastated and 80 million trees were overthrown, with many of them being charred or burnt. It had been unclear for a long time as to whether the great explosion was due to a comet, an asteroid, or something else.
Authentic specimens were obtained in a 1991 expedition to the Tunguska area site.
