Nevado San Francisco, or Cerro San Francisco (Spanish pronunciation: [neˈβaðo/ˈsero saɱ fɾanˈsisko]), is a stratovolcano on the border between Argentina and Chile,[3] located just southeast of San Francisco Pass. It is considered extinct and is one of the several 6,000 m (19,700 ft) peaks in the area, of which the chief is the Ojos del Salado. It is on the border of 2 provinces: Argentinean province of Catamarca; Chilean province of Copiapo.[4][5][6]

The volcano is part of the Central Volcanic Zone of the Andes[7] and reaches an elevation of 6,016 metres (19,738 ft).[8][4][a][b] It is composed from andesite with the exception of basaltic cones and lava flows on the eastern side. These cones are part of the Peinado lineament and a sample was dated 200,000 years ago by argon chronology.[15]: 74–75  They are noteworthy for their olivine phenocrysts.[7] One lava flow less than one million years old reaches a length of 11 kilometres (6.8 mi).[16] The western slopes contain dacitic lava domes.[17] On the summit lie two circle-shaped constructs, of Inca or Formative period ages.[15] San Francisco was first climbed by Walther Penck (Germany) on 16 December 1913.[18]

  • ^ The height of the nearest key col is 4,911 metres (16,112 ft),[14] leading to a topographic prominence of 1,124 metres (3,688 ft) with a topographical dominance of 18.62%. Its parent peakisOjos del Salado and the Topographic isolation is 34.8 kilometres (21.6 mi).[13]
