- ItemHuentelauquén coastal groups in the Andean highlands? An assessment of human occupations of the Early Holocene in Salar de Pedernales, Chile (26°S, 3356 masl)(2022) López, Patricio; Carrasco, Carlos; Loyola, Rodrigo; Flores-Aqueveque, Valentina; Maldonado, Antonio; Santana Sagredo, Francisca; Méndez, Víctor; Díaz, Pablo; Varas, Daniel; Soto, AngélicaWe present new evidence obtained in archaeological surveys in Quebrada Pedernales (3356 masl), in the southern puna of Chile (26°S; 69°W). A series of surface findings such as large lanceolate stemmed projectile points and geometric stones, together with chronostratigraphic and artifactual data recovered in excavations at the Pedernales-38 site, suggest that the coastal Huentelauquén groups explored and inhabited the Andean highlands between 10,151 and 9695 cal yr BP. The archaeological record is discussed as it relates to the known evidence for this cultural complex, recognized principally on the Pacific coast. The archaeological findings allow us to broaden the diversity of environments exploited by coastal populations of the Early Holocene, and provide new data on their mobility and settlement strategies.
- ItemTechnological and Protein Residue Analysis on Ancient Stemmed Projectile Points of the Southern Andes Highlands(2024) Loyola, Rodrigo; López-Mendoza, Patricio; Carrasco, Carlos; Walker, Cam; Fagan, John; Méndez Muñoz, Víctor Andrés; Santana Sagredo, Francisca; Flores Aqueveque, Valentina; Soto, AngélicaWe present the results of technological and protein residue analyses of the lithic assemblagesrecovered at the Pedernales-38 site (26.5°S; 69°W), located in the highlands of the southernAndes (3380 masl). Based on a reconstruction of the operational chains and the differentialrepresentation of their phases, we suggest that the final production, use, maintenance, anddiscard of large stemmed projectile points occurred at the site. Of the assemblage studied, nine(9) projectile points and one end-scraper were subjected to residue analysis using cross-overimmunoelectrophoresis (CIEP). Four positive reactions to antisera of human, camelid (guanacoor vicuña) and canid (Andean fox) were recorded. The results are discussed based on thedepositional context and the structure of the archeological record. We propose that Pedernalesprojectile points were mainly used in hunting weapons to capture wild camelids during theseasonal occupation of the Andes highlands
