Geology

The mountain range is a massif of volcanic origin from the Cretaceous period (from 145 to 66 million years ago) and later covered by a layer of calcareous sediment of marine origin, this means that the entire mountain range was once submerged under the sea and in mostly inhabited by corals that left their sediments.
The mountain range is formed by a complex of tectonic faults resulting from the collision of the Caribbean and Atlantic plates, rising and leaving the sea. This means that we can find rocks at more than 2000 meters high that at first glance can be seen remains of ancient corals that were in the sea.
