The Tunguska Event
The largest explosion in recorded history flattened 830 square miles of Siberian forest — and nothing has ever been found at the impact site.
On June 30, 1908, a massive explosion over Siberia's Podkamennaya Tunguska River flattened roughly 830 square miles of forest with a blast estimated at up to 50 megatons. No impact crater or meteorite fragments have ever been found.

- →Trees were found flattened in a distinctive "butterfly" pattern radiating from ground zero, still visible in expedition photos.
- →Despite the enormous blast, no impact crater or confirmed meteorite fragments have ever been recovered.
