Conclusion
• Exploration and classification of complex, multivariate geographic phenomena are facilitated with interactive box plots and MLVs
• Management decisions related to rock art preservation are justified based on quantitative characterizations of rock surfaces
• May prove useful outside of the rock art preservation community
