Chesapeake & Ohio Canal National Historical Park
Environmental Factors

The C&O Canal National Historical Park is in a constantly shifting, dynamic state. Weather and climate change, geologic processes, flooding and human-caused factors such as air and water pollution are only a few of the agents of change that have helped to carve the Potomac River Valley. The park provides a "living laboratory" that helps us better understand how these environmental factors have shaped park landscapes and ecosystems. Park staff carefully monitor changes in environmental factors, and can often alert managers to threats to the resources in time to preserve those resources.

Did You Know?
The Paw Paw Tunnel is 3,118 feet long and is lined with over six million bricks. The 3/4 mile long tunnel saved the canal builders almost six miles of construction along the Paw Paw bends of the Potomac River. It took twelve years to build and was only wide enough for single lane traffic.
