This past weekend we visited The Maras Salt Mines that have
existed since the preinca times. They are fed by a natural hot spring that
washes out salt deposits from the mountain. These deposits are the result of
isolated ocean waters drying up during times of massive geological change. When
we looked at the rocks surrounding the hot spring, we found tiny seashells. The
salinity of the water was 30% and much more concentrated than the ocean. We
were able to try the water because the bacteria that normally would get us sick
could not survive. The hot spring travels through various levels of salt planes
where the stream would be cut off by a rock and plastic to let the water
evaporate and leave the salt behind. The first layer of each plot is considered
the finest salt and is most often used for finishing dishes. The lower levels
of salt are more often used as medicine for animals or bath salts. Each bed
could be harvested up to once a month!
