Licancabur volcano

Laguna Verde (Green Lake) is possibly the most spectacular of the mineral lakes in the region. The colour is said to be due to an unusually high concentration of arsenic and changes according to the time of day and wind conditions; it also means the lake stays liquid even at temperatures as low as -20ºC. Licancabur volcano (5915m / 19,410ft) in the background sits in the extreme south-west corner of Bolivia on the Chilean border.
