Information about the Society

The Geological Society of Washington (GSW) was founded in 1893 to promote the increase and dissemination of geological knowledge. GSW provides a forum for geological interchange through a program of regularly scheduled formal talks, informal communications, opportunities to meet colleagues, field trips, and public service. Members represent a wide cross-section of the local geologic community including geoscientists from federal (U.S.Geological Survey, NASA, NSF, military, DOE, EPA) and state government, Congress, Carnegie Institution of Washington, local universities, museums, consulting firms, earth science educators, and others interested in the geological sciences. Guests are welcome.

The Centennial History of the Geological Society of Washington tells about the history of Earth Sciences in Washington, D.C. as well as the development new ideas in earth science and the evolution of the U.S. Geological Survey. The 165-page paperback volume contains stories about the intellectual and social life of scientists in Washington, and about the good-natured banter that has always characterized GSW meetings. As one reviewer put it, " Bonhomie has been a feature of the Society". A former Chief geologist of the USGS said, "The best $10 I ever spent!". The price is still $10, and the book can be purchased from:
