See the fascinating way salt is created in Peru

Take a look at the photos above for an intimate view inside Peru's salt mines. Going as far back as the Incas, the people of Peru have used this ancient technique to gather natural salt from the sea.

Hundreds of ponds have been built on terraces for water to flow into, where it slowly evaporates leaving the salt behind. The ponds are faithfully looked after by many locals, who have cared for the ancient ponds for generations.
