We may not have the Rockies in our back yard, but we have the roots of mountains that were as high as the Alps. Although local earthquakes are rare now, this area broke in two twice and an ocean flowed in. The C&O Canal's geology tells a story as fascinating as any place on the planet. Callan Bentley will use rock evidence to deduce geologic history of our region. The River Center is open Saturdays and Sundays from May 3 through October 26 from 10 am ?til 2 pm for tours of the lockhouse and interactive exhibits. Inside the River Center, the Conservancy installed a new exhibit, ?Backyard to the Bay,? that connects what happens on the land and the health of the Potomac River and the Chesapeake Bay. Visitors are guided by the Potomac Conservancy?s volunteer docents who lead tours, answer questions and discuss the historical and cultural significance of the C&O Canal and the Potomac River to the regional economy and the local quality of life. For additional information about the River Center at Lockhouse 8, contact Bridget Chapin, [masked] or visit www.potomac.org.
