Title: "Wetumpka Impact Crater, Understanding Alabama's Greatest Natural Disaster"

Speaker: David T. King, Jr., Professor of Geology, Dept. of Geosciences, Auburn University

Abstract: About 85 million years ago, the shallow waters of the Gulf of Mexico covered southern Alabama, including Elmore County.  These shallow waters were the target of impact for an approximately 380-m diameter chondritic asteroid body, which was traveling at about 20 km/sec.  The detonation of the impacting asteroid was a locally devastating event that opened a crater 5 km x 7.5 km in size that still persists today as a remarkable feature of the Alabama fall line area.  This presentation summarizes much of the research over the past 25 years by me and my students (10 M.S. students and 1 Ph.D.).
