Great view of Carcote salt lake and Aucanquilcha volcano (6174 meters above sea level) in the Background, and FCAB train in route to Ollagüe. See this photograph (RP #442265) of the same place, but to another train and another time. How to change the colors of the salt and the environment, depending on the time of year: http://www.railpictures.net/photo/442265
