Description
"Rock art, a modern misnomer that originated in Europe, is a categorical term that includes purposeful human modification of in-place rock surfaces by pecking, scratching, incising, engraving, drilling, carving, grinding, and painting to produce preconceived images. Thus, the bedrock grinding surfaces resulting from grinding activities to produce seed flour are not considered rock art, nor is a decorated pebble considered rock art."
