Ancient Indian pictographs (rock paintings) and petroglyphs (symbols carved or pecked on rocks) are claimed by some to be forms of writing for which meanings are known. However, are such claims supported by archaeology or by Native Americans themselves? Mr. Dart illustrates southwestern petroglyphs and pictographs, and discusses how even the same rock art symbol may be interpreted differently from popular, scientific, and modern Native American perspectives.

Presented by the White Tank Conservancy, this is the second program of three that will focus on the White Tank Mountains history, ancient peoples and petroglyphs and geology and plant life. Registration required.
