The word Sairécabur is the Castilianization of the Kunza name used by the Atacameño (also known as Likan Antaí) people to refer to the volcano: saire - rain, cabur - mountain, thus meaning "Rainmountain". Cerro Sairécabur 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.
The Receiver Lab Telescope (RLT) is located on Cerro Sairécabur, at am altitude of 5,525 m (18,127 ft).
