Sairecabur

The Sairécabur volcanic group is a volcanic chain directly south of the Putana Volcano, on the border between Bolivia and Chile. It contains at least 10 postglacial centers, the highest of which is Cerro Sairécabur at 5,971 m (19,590 ft). The complex includes the mountains Cerro Saciel and Cerro Ojos del Toro, directly north of Sairécabur, as well as the stratovolcanoes volcán Curiquinca (5,722 m (18,773 ft)), volcán Escalante or El Apagado (5,819 m (19,091 ft)) and Cerro Colorado (5,728 m (18,793 ft)), about 12 km (7 mi) to the north of Sairécabur. The complex also counts a number of abandoned sulfur mines, among which the "azufreras" Saciel, Ojos del Toro and El Apagado.

The word Sairécabur is the Castilianization of the Kunza name used by the Atacameño Likan-antay people to refer to the volcano: saire rain, cabur - mountain, thus meaning "Rainmountain". The Cerro Sairécabur edifice rises at the northern end of a 4.5 km wide Caldera which is breached and intersected on the north-end by a 500 m (1,640 ft)-wide volcanic crater. It is also the location of the Receiver Lab Telescope (RLT) at 5,525 m (18,127 ft).
