Teen’s Summer Craft: Petroglyphs
Petroglyphs are ancient rock carvings created by chipping, incising, or pecking
away the dark outer layer (desert varnish or patina) of a rock to reveal the lighter
stone beneath. They serve as vital historical and cultural records of indigenous peoples
worldwide, depicting animals, humans, geometric patterns, and spiritual symbols.
