Connecting People and Place in Utah through the study of archaeology. Rock imagery is human made marks on natural, non portable rocky surfaces. Pictographs were produced by the application of paint onto stone; made using a variety of pigments mixed with organic binders. Petroglyphs were produced by cutting away at a rock surface. People pecked, scratched, abraded, and carved images onto stone, usually removing dark weathered surfaces or patina, to expose the lighter rock beneath.
