6. Mountains of Potosi, Bolivia
Bolivia is blessed with the Andes mountain range and one of its highlights is the incredibly towering, red and the impeccable conical shape of Potosi’s Cerro Rico or also known as Rich Hill. Potosi is known as a haven of pure silver so consistent mining was prevalent for the past 500 years. Efforts are now being exerted to preserve Potosi as it is in danger of being worn out.
