About
About Piedra del Águila Petroglyphs (Atuel Canyon)
Basalt boulder field (5,000–500 BP) along Atuel River canyon 60 km south of San Rafael, Mendoza: >800 petroglyphs pecked on 3–5 m basalt columns produced by Pleistocene Atuel volcanics, featuring Patagonian–Espinazo style meanders, tridents, spirals, human tracks and camelid herds carved with quartzite points (500–1200 CE Agrelo–Viluco). Humberto Lagiglia 1960s documented Atuel I–III sequence bridging Andean Farmer vs Patagonian Hunter art; night photography reveals patina bands. Free-access river canyon site, chronicles late Holocene art transition.
Why it mattersMost intensive petroglyph field in Cuyo–Patagonia transition; defines Agrelo late Holocene style; natural laboratory for Patagonian vs Andean interaction studies.
