Indifferent Obliteration of Petroglyph Art

Petroglyphs are often found superimposed by other petroglyphs, but in some cases they have also been (partially) obliterated by hammering, rubbing or polishing of the rock’s surface. This short study investigates a number of cases in North and South America where petroglyphs may have (and in some cases definitely have) been obliterated by such grinding activities. This study therefore strongly recommend to accurately record instances where grinding activities took place, even when there are no petroglyphs visible.
