Cerro Ascotan

Cerro Ascotan (also known as del Jardin[3]) is a volcano on the border between Chile and Bolivia. It is 5,473 metres (17,956 ft) high,[1] 1,770 metres (5,810 ft) above the terrain and a maximum slope in the summit area of 26°. A breach in the edifice is 1.9 kilometres (1.2 mi) wide and 3.4 kilometres (2.1 mi) long, with an azimuth of 252°.[2] The current snowline lies between 5,700–5,900 metres (18,700–19,400 ft); during the Pleistocene it was lower at 4,900–5,000 metres (16,100–16,400 ft).[4] The volcano's summit, about one third thereof, was removed by a large explosion,[3] with debris thrown at large distances.[5] Volcanic activity probably occurred during the Pleistocene.[1]The volcano is neighbor to Cerro Araral.
