Dr. Ray Anderson, a retired University of Iowa Earth and Environmental Studies professor, will present here about the impacts of a meteor crater that hit Decorah over 460 million years ago! Join us for a geological story that has been revealed by various avenues of research and is known to be the second largest mass extinction, in terms of the number of species, on planet Earth. This remarkable set of discovered lifeforms is so unique that it has been named the Winneshiek Lagerstatta. Come see fossils of life that once lived on the edge of the sea. M $8; NM $10.
