The FCAB train goes around the great salt flats of Carcote (See in RP photography ID #390236 : http://www.railpictures.net/photo/390236), a rich deposit of various salts (chlorides, chlorates, nitrates, nitrides, boron, borax, lithium, etc.). Then comes a line through the middle of the salt, and then get to Ollagüe. In the background, we see the Aucanquilcha volcano, of 6174 meters above sea level.
