DESCRIPTION

This is a hilly part of the Inverigo area, unique in its hydrogeological characteristics as well as in its nature and landscape. The gorge is a natural split within the conglomerate rock formation of the Lambro River (Il Ceppo del Lambro), which has always offered cool temperatures to the inhabitants of Inverigo during the hot summer season. Along the route through the area, it is still possible to see the sites of extraction of circular blocks of stone, which were used as millstones, and some petrifying springs whose water is rich in carbonates which deposit calcium carbonate, encrusting the surrounding vegetation and creating evocative shapes and trays of stone.

INSIGHT

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.

CURIOSITIES

Descriptions of and routes around the conglomerate rock formation of the Inverigo Gorge may be found in historical guidebooks of upper Brianza (such as that of Curti, 1872), testifying to the importance which was attributed to them.

HOW TO REACH THE SITE

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.
