PIX4583798: Tunguska event -Artist view-3/3 - Tunguska valley - Artist view (3/3) - Artist view of the Tungouska region a few minutes after the explosion, June 30, 1908. 2000 km of forest and taiga were destroyed, blown by the shock wave of the car. Precisely what the Tunguska Event was remains a mystery. Despite the enormous scale of the explosion, there was no impact crater. Instead some 2000 sq/kms of taiga forest was flattened like matchwood and incinerated. This is the scene some minutes after the explosion. Most of the forest has been blown away, the few remaining stumps are burning and the air is full of acrid smoke. June 30 190 / Bridgeman Images
