Abstract

Abstract: The Rock Art Stability Index (RASI) is a rapid, quantitative approach to rock art condition assessment. Research carried out at Petrified Forest National Park, USA, demonstrates that, following a 2-day training session, site evaluators obtained replicable results, facilitating a condition assessment of over 3500 engraved panels. Two electron microscopy case studies allowed us to identify the specific rock decay processes and major causes of destruction on panels that were RASI-scored as in high threat, suggesting potential avenues for future conservation interventions. This approach illustrates a holistic strategy for rock art conservation. Highlights: Rock art management requires condition assessments Traditional condition assessments are analytically idiosyncratic and non-quantitative Specialized equipment is required to evaluate panel decay in condition assessments Rock Art Stability Index (RASI) is a low-cost, rapid and quantitative alternative New data show replicable results and comparability to electron microscopy analyses
