Late Pleistocene human occupations in the southern puna, Chile (12,4–10,7 ka cal. BP): Primary results from the Salar de Infieles (25°S, 3529 m. a.s.l.)
This article presents the results of excavations at the Infieles-1 site, located at 3529 m. a.s.l. in the Salar de Infieles (25°S), highlands of the Chile's southern Puna ecoregion. An initial human occupation was discovered next to an ignimbrite rock-shelter at a depth of 70–80 cm on top of a volcanic ash deposit, dated between 10,798 and 12,440 cal yr BP. The archaeological record consists of lithic wasted-flakes and knapping debris, an ultra-marginal andesite side-scraper, vicuña bone fragments and traces of red mineral pigment. As far as now, this event is the first human occupation recorded in the southern Puna. It is a camp associated with more favourable environmental conditions during the late Central Andean Pluvial Event II (CAPE II).
