Guitarrero Cave: A stratified cave site of long occupation in the Callejón de Huaylas in northern Peru. It was occupied in the Preceramic period (c 12,500-6000 years ago) and continued through later ceramic periods, showing domesticated lima and common beans by c 8000 BC. A wide variety of artifacts, lithic and organic, in Guitarrero I (10,610 @ 360 bc) contains flaked tools similar to the Ayacucho complex and Tagua-Tagua. Stemmed points similar to those in Lauricocha II were found in the same level. There is evidence that the site was occupied by hunter-gatherers and that the subsistence was transhumance. The dates of some human bones, if dated correctly, represent the earliest human remains yet found in South America. Guitarrero II has produced a series of radiocarbon dates covering the period c 8500-5700 BC and contains bone and wood artifacts, basketry an loosely woven textiles, and the willow-leaf projectile point.
