Cover Story: Cahuachi was the major ceremonial center of the Nasca civilization, which spread its dominance over southern Peru under the influence of a theocratic elite (100 BCE–500 CE). According to a geoarchaeological hypothesis, the site was struck and destroyed by three El Niño events which would have occurred around 100 BCE, 600 CE and 1000 CE, respectively. At the end of the series of events, Cahuachi would have been buried by a cap of alluvial deposits. Optically stimulated luminescence (OSL) dating of these deposits allow us to evaluate the literature hypothesis. Since the obtained ages are older than the Holocene epoch, the hypothesis must be rejected. A number of pieces of geological evidence corroborate this result. Further research is needed to better understand the end of Cahuachi and the Nasca civilization. View this paper
