Description

Morphology

Large semicircular cave, 20 by 12 metres, with large blocks on the western side.

Hydrology

Largely occupied by water, though shallow.

Other details

Excavated by marine erosion, favoured by the alternations of poorly consolidated conglomerate and lutites, corresponding to the Quaternary alluvial fan (Upper Pleistocene).

History

Known since time immemorial by the fishermen of the area, who used it as a visual reference to locate underwater fishing spots.

In the list of coastal caves of l'Ametlla de Mar (Faura, 1909: Ferraté, 1918) this cavity does not appear.
