Earth History of the National Capital Region

For over 120 years, USGS has studied and mapped the National Capital region revealing a rich and diverse geologic past. Join us July 6 in Reston, Va., and learn the story of the formation and destruction of continents and oceans, the eruption of ancient volcanoes, climatic and sea level changes, as well as the hazards of modern landslides, earthquakes and karst.

Caves, Sinkholes and Springs

Soluble rock layers called “Karst” exist throughout the nation. While Karst aquifers produce half the nation’s drinking water, rock layers underneath karst dissolve easily sometimes creating sinkholes that threaten life and property. Join us May 4th to learn more about this unseen world beneath our feet.
