ALMA dwarfed by Licancabur

These are the Antennas of the Atacama Large Millimeter/submillimeter Array (ALMA), on the Chajnantor Plateau in the Chilean Andes. The large antennas have a diameter of 12 metres, while 12 smaller antennas with a diameter of 7 metres make up the ALMA Compact Array (ACA). This site is located at an altitude of 5000 metres and the looming structure in the background which dwars even this is the volcano Licancabur.
