Cobalt mines of horns-Usseglio (TO)

Cobalt mines of Punta horns are located on the left bank of the valle di Viù set among the vallone del Servin and the Veil.

The whole of the Mineralogical localities is shot by order of the Municipality of Usseglio (TO) prohibiting research, collecting minerals and access to work sites abandoned, this Ordinance and better specified in the appropriate section on this web site (bans-Ordinances and resolutions on minerals in Piedmont).

We arrive near the cobalt mines of Horns, Tip of Servin, Ovarda Tower, side by a footpath that leads from Large easily accessible by the road that goes from Chiandusseglio in the municipality of Lemie (Turin).

Come to Costa fiorita, the trail crosses the Ovarda Tower, crossing the Devil's Channel, until the wind Crest.

The show of landscapes will ease the fatigue on the legs of almost 4 hours of travel.

From wind Ridge, continue for about 1 km in the direction of the Red Channel, we are below the top of the Tower of Ovarda and across the majestic Punta horns.

The stretch of trail that da Costa Fiorita leads us to the Devil's Channel is advisable to use protective helmet, ibexes often make rolling the stones from the overlying flounces.

By cantieri della Speranza, cross the upper part of the Valley of Servin in the direction of Punta horns which is clearly visible before our eyes, it is possible to reach the Valley of the Veil through the Hill of hope but we recommend the alternative route from to. Bessanetto, the ascent and descent from the Hill of hope exposes at high risk of the feasibility, safety must always take precedence over everything.

Several galleries names and levels of Cobalt mines of horns, remember Carlo Emanuele mine, la Cava del Prete, the St. Francis and the Pozzo di Giacomo Adorno.

The mines were discovered in 1753 and the Licences January 17, 1772 Regie were granted to the Earl of Rebuffo Traves [1].

As we have already seen for the mine of Crovino in val di Susa, mineral extraction was aimed at the pottery industry for the use of the pigment Cobalt Blue ' ' ' '.

For further information, the writers advise reading the book RED EARTH, GREEN and COBALT BLUE STONES curated by Maurizio ROSSI and Anna Gattiglia, volume published in 2011 by the Museo Civico ' Alpine ' Arnaldo Tazzetti '' by Usseglio in co-Edition with the Dipartimento di Scienze Petrological and Mineralogical of the University of Turin and with the Biblioteca Nazionale Universitaria di Torino.

We recommend visiting the beautiful Museo civico di Usseglio (TO), from years who runs the Museum, have authoritatively addressed, in all respects, dedication, care and protection of a unique and majestic mining environment, good.
