The Comet Research Group and I developed this presentation on the Younger Dryas Impact. I have long thought such a show should be made "open source" so any interested science geek could give the presentation to a local astronomy or geology club, rotary, classroom, or whomever you like. Or to just to review the subject in a linear graphical nature by yourself. I'd like to think this effort is the current state of the art, so to speak. It will be modified and improved as the evidence for the cataclysm continues to pile up, and there is a larger and more extensive version coming I welcome your suggestions for modification and improvement. But for now, have at it, and let me know what you think. I plan to "annotate" this and future efforts when I have the time. George Howard ~~ @cosmictusk www.cosmictusk.com www.cosmicsummit.com

 UNUSUAL: extinct species had lasted for millions of years

41. Abandonment of Topper, SC Quarry
 Many Spherules atop Clovis points and debitage
 No spherules below Clovis points and debitage
 Snapshot: impact right after chert was dropped
 Quarry abandoned for ~500 years or more

42. 12,800 years ago,
At the time of the impact
More than half the people
in the
Northern Hemisphere
Vanished! Imagine that.

43. So,
Where
Did the
Clovis
People
Go?

Any Evidence?

45. Comet Shoemaker-Levy
 99%+ of comets break into fragments
 Hit planets (Shoemaker-Levy, 1994)
 Could one have hit Earth?
So, What Happened?

46.  We think a huge Comet Swarm hit the Earth
 Fragmented comets are very common
 50 in last 150 years = every 3 years
