- Abstract:
-
The Chesapeake and Ohio (CO) Canal National Historical Park is unique in that it is the only land within the National Park system that crosses 5 physiographic provinces along a major river. From Georgetown, District of Columbia (D.C.) to Cumberland, Maryland (Md.), the CO Canal provides an opportunity to examine the geologic history of the central Appalachian region and how the canal contributed to the development of this area. The geologic map data covers the 184.5-mile long park in a 2-mile wide corridor centered on the Potomac River
- Purpose:
-
The geologic map data was intended to help the National Park Service address Natural Resource Inventory and Monitoring programs within the park. In addition, this data may be used to provide the public with a better understanding of the geologic setting in a National Park that spans five physiographic provinces.
