Dry alcoves and sheltered walls preserved what a wetter climate would have destroyed: sandals, baskets, cordage, wooden tools, painted figures and the debris of daily life. Archaeologists working with museum collections, radiocarbon dates and the knowledge of descendant communities have turned that record into a history reaching back thousands of years.
These pieces explain what has been learned and how, and they cover the work of keeping sites intact, from reading rock art without touching it to the volunteers who record change over the years. None of them says where anything is. For the land and the laws around the sites, see Public lands and conservation.
