I am taking some liberty in attaching an article published in the September 2012 issue of GSA Today. The title is "Future volcanism at Yellowstone caldera: Insights from geochemistry of young volcanic units and monitoring of volcanic unrest." Please do note that this article is under copyright by The Geological Society of America and I pass this along for your reading only.
