The Place, Evolution, and Rock Art Heritage Unit (PERAHU) at Australia's Griffith University is dedicated to the research and preservation of Australian rock art, as well as rock art and human evolution research internationally. As the site mentions, there are approximately 100,000 individual rock art sites in Australia, but no national database has ever been established, and there is, of yet, no coordinated approach to documentation. After perusing the homepage, readers may like to select the Protect Australia's Spirit section and watch a short but engaging video that reviews the state of the nation's rock art and PERAHU's mission. Beautiful images of rock art adorn the page. There are also fascinating stories of the researchers and community members involved in protecting these sacred cultural artifacts.
