The Manson Meteor Crater

Saturday, April 2, 2011

The bedrock beneath Manson, Iowa, has been known as a region of unusual geology since 1912 when samples collected during the drilling of a town well at Manson proved to be unlike other rocks in the area. The nature of the anomalous geology remained a mystery for decades. In 1966, evidence was discovered proving the Manson Structure was caused by an ancient meteor …a huge meteor!  Manson crater expert, Professor Ray Anderson with University of Iowa Department of Geology, will discuss the interesting geological history, the stories of discovery, and the unfolding body of knowledge regarding the Manson crater and its impact on the region.  The presentation will be followed by telescope viewing, weather permitting.
