The key to life

Tolar Grande, sea eyes, stromatoliths and the origin of life: plenty of reasons to visit this beautiful place.


There are two ways to get to know a place. The first is simply wandering, walking around, seeing what our eyes show us — which is not a little —. However, by limiting our experience to what we can perceive according to our own parameters, we are missing things.

The second also allows us to enrich ourselves, take something from the place we visited. Oh, how? Studying, reading, talking to local people or, better yet, with guides. That way, let's see what we really have to see in that place, that our senses would have overlooked without someone pointing it out.

In   Tolar Grande  (Salta) , the “  eyes of the sea ” make up one of the most unforgettable walks in the  Puna . In the middle of the  salt garden, the direct perception of these natural mirrors of water — and of the surrounding flora and fauna — is in itself wonderful. However, the most amazing thing about that place is its  microbes and bacteria .

Without prior warning, we would miss the  stromatolites , clusters of microorganisms with algae, linked to calcareous formations such as those that inhabited the Earth  3500 million years ago. They were the ones who created the conditions for life on the planet: they were responsible for capturing carbon dioxide and transforming it into oxygen .

 Tolar Grande, sea eyes, stromatolites and the origin of life: there are plenty of reasons to visit this beautiful place and, in the passing, learn how we got here.
