Chiusella Valley
Montaju-Vico C.se (TO)

Starting location Traversella (TO), via delle miniere, car park piazzale Cava Grande New 850 metre height.

Arrival, location Montaju district municipality of Vico Canavese (To), about 1850 meters height.

1000 meters in altitude.

Recommended period June.

Challenging path.

The Valchiusella occupies the upper Canavese to Ivrea North-West and is crossed by the Chiusella River tributary of the Dora Baltea.

Located in Valchiusella, Traversella is a picturesque village which is about 60 km from Turin (Turin).

Excellent base camp for excursions of alpine tours and busy resort.

The territory of the municipality of Traversella is visited by experts and fans of Mineralogy.

A good part of the story of the charming Traversella is linked to the mines.

Alpine mountain range formed about 50 million years ago.

Under the Valchiusella, about thirty million years ago, a volcano trying to rise to the surface with his molten magma.

Volcanoes that fail to reach the surface are called '' PLUTONS '', and the rocks that are formed when they solidify are called '' intrusive rocks. ''

The Pluto was forced to cool without being able to vent his strength, forming the mountain now called Betogne, and its heat melted and modified the rocks all around.

After millions of years, the erosion of the rocks brought to light the Pluto solidified.

This magma solidified millions of years today is extracted from the quarries of Traversella, Brosso, and Vico and is called diorite.

During the eruption went up along with the underground magma minerals that settled in rich strands arranged around Mount Betogne, and in particular in Brosso and Traversella.

Countless ascents travelled by the author from Traversella towards Montaju.

Between the Valley of the Bersella and Included, North of Traversella, Montju rises (Monte Acuto) toponym indicating a pyramid-shaped mountain with the pointy end, the surrounding area is located in the municipality of Vico Canavese (Turin).

The two ravines which we are among the most savage of Valchiusella.

After the old plants Traversella mines, continue in the direction of the diorite quarries until you meet a bridge that will enable us to cross the Bersella stream that hugging in the thick of a hazelnut Grove to meet small piles of stone (men).

From this landmark turn left leaving the Creek and the darkness of the hazelnut Grove.

The increasingly uncertain and clearly visible only in May and June, is difficult conditions during the summer months due to the presence of tall ferns that despite being evocative conceal already uncertain path that abruptly goes back in the direction of the Included.

For about 300 meters in altitude, the trail gets lost in the woods of birches and chestnut trees along alternate stages the crestino between the bersella Valley and Included.

Left behind the forest we have Included ones and the Valchiusella will repay our efforts.

The trail continues through the thick grass and small outcropping rocks accompanied by beautiful Heather bushes (Ryan), on the bottom of the Valley is clearly visible a spur of triangular-shaped rock, Montju or Monte Acuto, this rocky triangle will be our reference point.

On the coordinates given in '' to '' little outcropping field to sulphides, the path cuts across the valley floor Included up to the ruins of old mining installations across Montaju years ago by master and domina Included ones on.

There are approximately 100 metres '' B-C-D-E-F-G-H '' ancient mines, up to altitude 1672 where he started a large capellaccio area '' s-L-M-N '' extending especially on the Bersella Valley until 1850 approximately altitude, these are classic Montaju deposits.

On the same side in '' or '' there is an old abandoned mine.

The trail continues through the Valley but it is preferable to retrace your route back retracing initially Included Valley from where it will not be difficult to find the trail.

Having regard to the State of disrepair of the mines, it strongly discourages visiting within them that are unstable, unusable and dangerous, common sense and safety must always take precedence over everything.

Traversella joints we recommend to visit the mining museum, those interested Traversella and for any information you can contact the Gruppo Mineralogico paleontologico of Valchiusella G.M.V.
