Figure 7A–C. Schematic graphics illustrating the evolution of the Cowpens National Battlefield landscape, continued. Three graphics depict three periods and events in geologic time that gave rise to the rocks and landforms at the park today. Caption follows.

Figure 7A–C. Illustration of the evolution of the landscape and geologic foundation of Cowpens National Battlefield. (A) In the Ordovician and Silurian, periodic collisions of volcanic arcs and microcontinents were building out the eastern margin of Laurentia. (B) By the Pennsylvanian, major continental collision pushed the Appalachians up to their highest point and all the accreted landmasses and thrust sheets were deformed and metamorphosed. (C) Since the Triassic, when the landmasses began to break apart, the landscape at Cowpens National Battlefield has been subjected to continuous weathering and erosion. Sediments are transported eastward to become part of the Coastal Plain. Graphics are not to scale. Colors are standard colors approved by the US Geological Survey to indicate different time periods on geologic maps and correspond to the colors on the geologic time scale. Map symbols are included for the geologic map units in the GRI GIS data.
