On the old banded sediments of the basal complex appears a raised beach 14 meters above the current sea level. This does not mean that the sea level reached so high and has now dropped so sharply. Something has, but it is clear that the island has also risen. They are white materials from the ancient marine plain with deposits from a sandy beach and pebbles, accumulated by the waves together with interesting fossils 4.8 million years ago.
It presents a multitude of cavities and recesses, of high aesthetic, geological and paleontological value, in which a large number of fossil remains are identified.
