A very special area in the mountains, one of many in the area. There were probably huge lakes in the distant past. It is now mined here. But what is behind the minerals?

Mexico City was built on the bottom of several dry prehistoric lakes. However, mining activities in the area are revealing the ruins of a very old but very modern urban agglomeration. What lies beneath the calcareous strata of the present-day city?

This time we will leave the stellar citadels and look at the inhospitable Atacama Desert near the border with Bolivia. This area is very interesting, as is the Chilean coast. We'll discover what lies beneath the disappearing limestone hills. A different, colourful and lost world... ???
