Photo Gallery

The 10-km-long, E-W-trending ridge that forms the broad summit of 6176-m-high Aucanquilcha stratovolcano consists of several overlapping volcanic edifices. This view overlooks the southern flank of Aucanquilcha from Puquois. The world's highest mine and permanent human habitation is located at the summit region of Aucanquilcha. No historical eruptions are known from Cerro Aucanquilcha, but postglacial lava flows overlie moraines on the upper southern flanks.
