The Potomac Geophysical Society (PGS) is the Washington D.C. area affiliate of both the American Geophysical Union and the Society of Exploration Geophysicists. Founded in 1973, the Society typically meets on the 3rd Thursday of the month from September through May for dinner at the Orchard Cafe Restaurant in the DoubleTree by Hilton, Tysons Corner, VA, and a presentation on timely topics in the earth sciences. Look for the glassed-in meeting room at the back of the restaurant.
