Geology encompasses so much more than rocks and minerals. The Susquehanna River is a unique body of water. Formed hundreds of millions of years ago, geologists have come from various places to study exactly how this river was created, along with the mountains around it. The Susquehanna has not always looked the way it does today, it continues to change slowly over time. Join Pierre MaCoy, P.G. Hydrologist 2 from the Susquehanna River Basin Commission, for a virtual presentation on the geology of the Susquehanna River. Links to virtual presentations will be sent the day before the scheduled lecture.
