Resumen de Old petroglyphs on the North American High Plains
Research into the ages of petroglyphs on the North American High Plains has revealed a pattern where Early Archaic (7500 to 5000 RCYBP) figures are pecked abstract designs that display a great deal of autonomy or individualism. Using the age of the Early Archaic petroglyphs as a guide, we have found sites with these early figures superimposed on older petroglyphs. In all instances the older figures are abstract incised patterns rather than the suspected representational forms. There appears to be a pattern where very old High Plains� petroglyphs include abstract figures.
