ABSTRACT
More than 100 years ago, a fireball appeared in the sky above Siberia and a huge explosion rocked the Earth, destroying 830 square miles of forest. Scientists are still arguing about exactly what caused the Tunguska Event, mainly because the cataclysmic event wasn’t investigated until 19 years after it happened. Siberia has always been a remote and difficult place to travel. Winter is brutally cold, with winter temperatures dropping to -30 degrees Fahrenheit. In the summer thaw, the ground turns into a mushy mess that makes travel very difficult. In 1921, Kulik was the curator of the meteorite collection at the St. Petersburg museum. When he read the old reports of the Tunguska event, he was sure it must have been a meteorite that entered Earth’s atmosphere.
