A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. The term should not be confused with petrograph, which is an image drawn or painted on a rock face. Many hypotheses explain the purpose of petroglyphs, depending on their location, age, and subject matter. Some may be astronomical markers, maps, and other forms of symbolic communication, including a form of proto-writing. Some petroglyph images probably have deep cultural and religious significance for the societies that created them; in many cases this significance remains for their descendants. Many petroglyphs are thought to represent some kind of not-yet-fully understood symbolic or ritual language.
