This is a tuffaceous rock (travertine) in the process of active formation, the result of constant contact between calcareous water and the surrounding rocks. Rainwater dissolves the limestone rocks predominating in the area. Upon emergence, carbon dioxide is released and calcium carbonate precipitates, forming layers of travertine. This process also creates grottos, cavities, and small caves.
