Rationale The Forty Acre Rock Study Site is an excellent example of a granite outcropping in the Piedmont of South Carolina. Many such rock exposures occur throughout the region, including the Winnsboro Blue Granite in Fairfield County, which is mined heavily as an economic resource and which has been designated as the official State Rock. Although Forty Acre Rock is not quarried, it represents a valuable resource nonetheless. As part of the Flat Creek Preserve, the granite is home to several species of rare plants and offers a truly unique biological habitat. The site is also near the boundary of the Sandhills and Piedmont regions and clearly illustrates landform features characteristic to each.
