Infiernillo

Infiernillo, a late-Pleistocene to Holocene basaltic andesite volcanic field along the Río Salado in Argentina lies about 70 km east of the crest of the Andes and NW of the town of Malargüe. Several vents controlled by extensional tectonics produced lava flows with prominent flow features that reached to the river. A radiocarbon date of about 8840 years before present was obtained from Volcán Hoyo Colorado.
