Petroglyphs, often called "rock art," are line carvings, etchings or drawings on stone that are commonly attributed to prehistoric people. Rock art is found in thousands of sites across America. The search for the meanings behind these images often leads to more questions than answers as petroglyph images may predate written and oral histories.
In 2004, University of South Carolina Archaeologist Tommy Charles, the Pickens County Museumn and a team of volunteers unearthed a group of petroglyphs on a rock outcrop in Pickens, South Carolina. Tommy and other archaeologists now struggle to understand the culture and ideas behind these mysterious images. Are they sacred motifs, historical records or artistic expressions?
