The Tunguska incident has always interested my curiousity. Though a lot of articles have claimed through tests and experiments that it was a asteroid
/ comet that impacted the site.
This was mainly due to Ground Zero does have a impact crater, and as one poster stated, they found common elements that support this theory.
But, if your like myself and enjoy HP Lovecraft, we can still write it off that a bunch of mad cultist summoned Azathoth, and the opening of his eye
caused the explosion.
The Call of Cthulhu RPG explains this and similar phenomena as the result of Outer Gods like Azathoth entering the Earth's reality
