Picture of the day on January 9, 2017: Location known as Ojo de San Pedro, El Loa Province, Antofagasta Region, northern Chile, close to the Bolivian border. The location, dried now, used to be a circular lake (therefore called "Ojo", to English "Eye"). The volcano in the background is San Pedro, a 6,145 metres (20,161 ft) stratovolcano.
