A few years ago my wife and I spent several weeks exploring the Bolivian Altiplano. Altiplano means high plane and is a plateau east of the Andes with an altitude above 3500 m (11500 ft). It is the most extensive high plateau on earth outside Tibet. Coming from the Altiplano in the west the land dropped down before the town of Tupiza. After many switchbacks we were suddenly rewarded with an amazing view onto a valley covered with cathedral rocks. An approaching storm added drama to the landscape spectacle in front of us.
