Clovis & Comet Impact Articles

'Clovis comet' researchers have a new theory postulating a major comet impact in north America. According to their interpretations, the "black mat" of Clovis times contains particles that can only be explained by extraterrestrial origin. Now comes the hard part, and that is asking the kinds of questions needed to establish the validity of the new research and (if confirmed) explore its implications:

First, was there really an extraterrestrial impact that brought an end to Clovis culture and changed the earth's climate? As skeptics have said over the years about a wide variety of claims, "Important .... if true." Is the postulation of a Clovis-age comet impact true? Many archaeologists and other scientists have raised vigorous challenges to the comet impact idea, and these challenges are still emerging and being refined.

Secondly, if a comet impact did occur, what might this mean, for both our understanding of specific events at the close of the Pleistocene, and our general theories of climatic and cultural change? What are the implications for archaeology including Southwestern archaeology?

At the 2008 Pecos Conference, we hope to make progress toward finding answers to these questions. A panel of scientists who made this potentially remarkable discovery will present the results of their research on Friday night, followed by a panel discussion on Saturday morning. Pecos participants will be encouraged to ask questions of our panelists in both sessions. It should be a lively and, we hope, informative debate.
