简介

My primary research interest are terrestrial impact craters, which are caused by an asteroid or comet smashing into the Earth. Perhaps the most famous example is the Barringer Meteor Crater in Arizona. Fortunately, we have two proven (Flynn Creek & Wells Creek) and two suspected (Howell Structure & Dycus Disturbance) impact sites in Tennessee. Over the past couple of years, Keith Milam, Jonathan Evenick and I made numerous trips to Flynn Creek. Keith's forthcoming paper on the central uplift and Jonathan's spectacular new structure map will add greatly to our understanding of the complex geology of the Flynn Creek impact crater.
