The Rio Tinto runs from the Sierra Moreno Mountains down to the Gulf of Cádiz in Huelva, Spain. Rio Tinto translates into red river and this is exactly how the river appears. High levels of iron in the water cause the red coloring of the river. The river has been mined for copper, gold and silver from ancient times, and continues as of today. The Rio Tinto has the oldest mines in the world, which are believed to be the fabled King Solomon’s mines. Due to all the mining, the river has a high acidic content and is home to organisms that survive in extreme conditions. This has led to scientific study of the river, used in the study of the underground lakes of Mars and Jupiter. The link to outer space seems appropriate, as the Rio Tinto area has an alien lunar like landscape. The mining has created walls of terraced rock that has formed a natural amphitheater. --
