Cerro Ascotan
21°41′S 68°07′W / 21.683°S 68.117°W[1] Cerro Ascotan (also known as del Jardin[2]) is a volcano on the border between Chile and Argentina. It is 5,500 metres (18,000 ft) high, 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°.[1] 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).[3] The volcano's summit, about one third thereof, was removed by a large explosion,[2] with debris thrown at large distances.[4]
