The research undertaken inside the Grotta della Cala examined the Neolithic level of the cavern’s Holocene stratigraphy. The presence of plain ware pottery decorated with simple red bands confirmed the layer’s cultural attribution.

There was a lack of finds in the Mesolithic layer and the stratum itself gradually thinned out towards the cavern’s interior, where it finally became totally depleted above a level of compact stalagmite. The latter is the roof-like surface of the “beta” stalagmite, datable to circa 30,000 years ago, which constitutes the base of the Gravettian – Epigravetian levels.

The stalagmite lies sloping towards the exterior of the cavity, the incline rapidly increasing in correspondence with the threshold between the grotto’s two chambers. Along the steepest tract of the stalagmite surface the Gravettian and Epigravetian layers form sacs and then diminish. (MiBAC)
