River Center at Lockhouse 8 (7906 Riverside Avenue), C&O Canal National Historical Park, Cabin John, MD 20818 (Directions)

We may not have the Rockies in our backyard, 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.
