May 3rd Program – Geology of the National Capital Region
Washington DC is a complex place rich in history, and we are not talking about politics. A series of geologic events has shaped the National Capital Region. Behind the landforms we see, there is a billion plus year story of tectonic forces – rifting and mountain-building, continental plates drifting and colliding , faults and shear zones, volcanism, metamorphism, erosion, etc. Geologically, the National Capital Region has long been and continues to be a work in progress.
Our speaker this evening is Scott Southworth, a Research Geologist with the U.S. Geologic Survey, who will talk to us on the geologic processes that have shaped the region. Scott received his BS from James Madison University and his MS from the University of Maryland. His main areas of research interest include geologic structures and history. He is a Fellow of the Geological Society of America and is the Project Chief and Principle Investigator of the Appalachian Blue Ridge Project (APRP). The ABRP is an ongoing comprehensive effort to clarify the complex structural, metamorphic, and geomorphic evolution of the Southern and Central Appalachian Blue Ridge Province. The project is collaborative, involving multiple USGS Regions, State Geological Surveys, and academicians from seven universities, and involves detailed and regional-scale mapping, geochronology, petrologic and petrographic analysis. Scott is the author of numerous professional journal publications and an accomplished lecturer, field trip leader. He serves as a science advisor to the National Park Service and has provided internship training to numerous undergraduate and graduate students from multiple universities throughout his career.
Please join us in taking Scott to dinner on May 3rd before the club meeting. We will be meeting at 6:00 pm at Elephant & Castle Restaurant, 1201 Pennsylvania Ave, NW, Washington, DC, about 2 blocks from the Smithsonian Institution National Museum of Natural History (NMNH) where our club meeting is held. If you cannot make it to dinner, we will meet in the NMNH lobby at 7:30 pm and will then head up to our meeting room for Scott’s presentation.
