The Atacama Desert in the north of Chile is rich in mysteries and minerals.
One of the mysteries is the meaning of the 5000 geoglyphs that
dot the desert.
The largest one is located just east of Huara, measures 120 meters and depicts a human figure or deity. This Atacama
Giant dates from around 1000 AD and might be an astronomical calendar or a signpost on one of the ancient Tiwanaku trade
routes. Or maybe something else?
After 1850 the worldwide demand for fertilizers and explosives soared. Both applications need nitrate, a mineral of which the northern Atacama happens to have the world's largest deposits.
Soon mining for the 'white gold' boomed and complete nitrate towns emerged.
It triggered the War of the Pacific, in which Chile conquered all of the Bolivian held Atacama territory.
Mining continued till the 1960s after which most of the nitrate towns and mines were abandoned and left to rust away.
Since 2005 the Humberstone and Santa Laura Saltpeter Works is a Unesco World Heritage site and open to the public.
We visited the Giant and Humberstone in September 2011.
