The Maya End of the World:
The Ninth Century Collapse and Climate Change

Professor of Archaeology

Moderated by: Cynthia Wichelman, M.D.


David Freidel

While the ancient Maya calendar continues to cycle forward and the Classic Maya never predicted dire consequences for completion of the 13th Baktun, the Maya of the southern lowland region of Petén Guatemala and adjacent areas did indeed experience a catastrophic change in their civilization during the ninth century AD. The nature of this change, dubbed the Collapse, remains a subject of scientific controversy among specialists. Over the last 30 years several important proxies of drought have been developed and implemented in the Maya lowlands and some scholars believe that they register drought episodes capable of precipitating the observed social catastrophe. These arguments will be reviewed and illustrated with a powerpoint slideshow, with plenty of time for discussion afterwards.

Science On Tap highlighted on St. Louis Public Radio and Voice of America!

Science On Tap is a place where, for the price of a beverage, anyone can come to explore the latest ideas in science and technology. Meetings take place outside a traditional academic context, in the Crown Room at Schlafly Bottleworks.


Meetings are held on the last Wednesday of the month during the academic year, usually from 7:00 - 8:30 PM. The standard format is as follows: 20 minutes of presentation, followed by a 7 minute break for attendees to introduce themselves to each other at the table, and then an hour of discussion. Seating is limited to the first 100 people.  No reservations accepted.
