explosion which may have killed N.A. megafauna
A likely explosion from the sky may have impacted North American megafauna, the Clovis culture, and altered climate 13,000 years ago, shifting focus away from primarilly human factors.
(also includes link regarding prehistoric human migration along the coasts 10,000 years ago. i have supported this theory.)
