Heard of the Köfels’ Impact Event?
I hadn’t before today. Apparantly the Sumerians witnessed and recorded it.
On 29th June 3,123BC (very close to the start of the ancient Mayan Long Count), an asteroid gouges a 2 kilometre cut out of the mountain overlooking Austrian Köfels, releasing 14,000 Megatons, “producing not a crater, but the demolition of the mountain into the gigantic landslide we see today.”
An event surely worthy of starting a calendar anew – even more so if there were multiple events of this type (my speculation).
The book has just been released, available at Amazon:
