Left Ala Valley
The Curbassera-Pian del Tetto-Ala di Stura (TO)


The Mineralogical localities of Curbassera is located on the left bank of the Val d'ala within easy walking distance of the borgata Pian del Tetto, Ala di Stura (TO).

The Curbassera is divided into small and Large Curbassera, Curbassera in both places large serpentine bench incase the rodingiti evidence of what was for excellence between the Mineralogical localities of Val d'ala classics.
From borgata Pian del Tetto, on the right towards the mountain, we take a marked trail that went straight in a beech wood takes us on location Credarian in less than 20 minutes.
After crossing a wooden bridge, beneath which flows the rio Curbassera steep, we are short at the foot of the little and the great Curbassera where in a small plateau will be a recreational area complete with benches and a fountain from which valuable abundant spring water gushes.

Just below us, a portion of Curbassera was used as a climbing gym.
Eastward in slope a few hundred yards back toward the main banks of the great Curbassera that occur up to the Ridge South of the confluence of the little Valley of Serpents.

North West you can see the Small fields Curbassera which is divided from the great from a steep channel where most Valley have been found discreet and rare samples of perowskite.

The Jervis in 1873 described a silver mine called Truccia and Pertus reporting chalcopyrite, minerals such as malachite, azurite, calcosina and erubescite.
Historical documents refer to the year 1344, (argentifere in Truccia Mines and Pertus under the beak of Corbassera.

Taking as a point of reference the Groove that splits the Curbassera and coming to the Northwest, without a trace of the path, we arrive in the Rio Curbassera valley bordering on the hydrographic left the small Curbassera.

This vast area has several deposits exploited since 1800 will not be difficult to notice them because the rodingite is strewn everywhere.
The flank of the Valley which borders the Small Curbassera can become dangerous in spring and early summer, large landslides will ruin this area, security must prevail before everything.

In the Curbassera literature is also known under the name of Courbassere Bills or Beaks of Curbassere.
