Abstract

Petroglyphs weather at varying rates, compared to the unengraved host rock into which they are carved. Most petroglyphs are significantly harder or significantly softer than surrounding rock, depending on the nature of weathering. Variability and intensity of weathering probably introduces error into radiocarbon, rock varnish and microerosion dating methods.
