Cerro Ascotan (also known as Spanish; Castilian: del Jardin) is a volcano on the border between Chile and Bolivia. It is high, above the terrain and a maximum slope in the summit area of 26°. A breach in the edifice is wide and long, with an azimuth of 252°. The current snowline lies between 5700-; during the Pleistocene it was lower at 4900-. The volcano's summit, about one third thereof, was removed by a large explosion, with debris thrown at large distances. Volcanic activity probably occurred during the Pleistocene.
