| Description |
| Rock Art is a term used for designs made on rocks or on the earth's surface by people in the past.Petroglyphs are designs made by carving or scratching away the dark layer of rock varnish on a rock's surface to reveal the lighter rock underneath. Rock varnish is a thin layer of tiny clay particles, which are deposited on rocks in desert environments. These clay particles are attached to rock surfaces by bacteria that live there. Manganese in the clay gives rock varnish a dark color. In time, the color of the exposed interior becomes more like the color of the surface because of the rock varnish's re growth.
