SALT FLATS


Hundreds of artificial ponds dot the hillside near the small town
of Maras, high in the Andes of Peru. The ponds fill with water
from a stream that runs down from the nearby mountains. In the sunshine, the water evaporates,
leaving behind a thick salt crust that can be collected. The people of Maras have been gathering
salt in this way for at least 500 years.
