Cation‐ratio dating has allowed us to obtain chronometric ages for 13 rock engravings from the Cima region, and an additional date from the Coso Range, eastern California, North America. These fourteen new dates, in combination with five previous dates from the Cosos and other lines of evidence, enable us to reassess the rock engraving chronology for eastern California. Rock engraving is indicated as beginning in the Late Pleistocene and continuing into the Historic period, rather than the short 1500 to 3000 year prehistoric spans of production previously hypothesized. Stylistic chronologies of curvilinear followed by rectilinear and representational motifs are also provisionally supported by our results.
