Right Ala Valley
Beccas of Arnas-Arnas The vallone del rio-Balme (TO)

The Valley is crossed by the Rio Arnas is among the most rugged and difficult to reach that branch out from Pian della Mussa.

You can easily reach her foot along the Roch Neil where a well marked trail leads us next to b. ta Ghiaire across the Venoni, the trail runs alongside the rock Turtle until you reach the pastures of Arnas.

The Mineralogical localities treated between the pastures of Arnas and Valley crossed by the Rio Arnas which goes up to Beccas of Arnas.

As a point of reference to find the exact location you will consider the Rio Arnas that at a point x of Vallone disappears under the gigantic pietraia.

The research area is to be considered dangerous, Beccas of Arnas in thaw period that coincides with the short period of the feasibility of vallone, drained his material often walls.

Beautiful samples of adularia with some rare titanite were found in pastures of Arnas shortly before embarking on the Valley crossed by the Rio Arnas.

Primary deposits are located in the walls below at Beccas of Arnas that several units make up the broad Valley and to a lesser percentage on the opposite side of the same.

They are present in the gravel pit, boulders with different mineralization that can be attributed to primary deposits Beccas of Arnas still partly visible in its walls.

Thanks

 

My heartfelt thanks to Istituto Geografico Militare in Florence that has made available the cartography of the area treated.

Thanks Franco Chianale for guidance and for allowing the author to photograph samples of treated.
