Terminal Clovis Update

Thanks to Kris Hirst, the About.com Archaeology Guide, for finding the presentations from the Pecos Conference about the hypothesis that a cosmic impact at about 12,000 years ago wrought worldwide havoc. I've touched on it previously; see here and here for background. The Pecos Conference was held from 7 to 10 August in Flagstaff, Arizona. Kris's post points to a YouTube playlist with video of a two-hour presentation on 8 August and a long panel discussion on 9 August. This is cutting-edge, mostly unpublished science presented in an informal setting. Treat it with an appropriate level of enjoyment and skepticism.
