Abstract

The application of a mixture of aluminum powder and water, rather than chalk, is proposed for photographically recording petroglyphs. The use of chalk is questionable due to its permanency, tendency to disfigure soft surfaces, indistinctness of line and non-light-reflecting properties. Petroglyphs should be photographed without additives whenever possible, but with good judgment aluminum powder can be used as a time- and labor-saving aid.
