History of Keynote Lectures at Dry Dredgers Meetings of the 21st Century

The Dry Dredgers was formed from a monthly lecture series at the University of Cincinnati in 1942. (See our page on how we began.) Since then we have continued the tradition of feature lectures on interesting topics of geology and science at our monthly meetings. We continue on continuously operating, providing lectures and supporting education and the paleontology into the 21st Century.

Here is a list of the topics presented thus far at our meetings in the current century.
