The cavities which form in fluvial conglomerates in the upper plains of Lombardia are also known as “pollen eyes”. The conglomerates (Il Ceppo) have a considerable carbonatic component in the pebbles, and phenomena of karst dissolution lead to the melting of the carbonatic cement which unites the pebbles, and to the dissolution of the clasts themselves. The majority of the cavities in conglomeration may therefore be attributed to karst phenomena, even though cavities of considerable size may also be formed by removal (usually due to piping) of changes within the conglomeration.
The area is currently located in a property to which access is not allowed. However, thanks to the helpfulness of the owners, guided visits along the gorge pathway are periodically organized.
