On February 3, 1885, Jean-Victor Fusinaz and his wife Marie-Reine Perrod decided to sell the Champterré alpine pasture in Rhêmes-Notre-Dame, located on a knoll "tzanté" above the pastures of Thumel.
This place is burdened with various legends that deter all potential tenants, stories of a malevolent manifestation:

In one version, the spirit is that of a little girl born with a deformed leg, who one day loses her balance and falls off the cliff adjacent to the alpine pasture. Her little body is never found, but from that moment on, her "tzante" singing and "ri" laughter are heard at night on the barn roofs, where cows are found with their tails knotted and horns stuck.

In another version, the evil spirit takes the form of a charming woman. It is said that in Fos, the village upstream of Champterré, live the most beautiful girls of the Rhêmes Valley. The young men from other villages, in an attempt to reach them, take the path that passes near Champterré. Along the way, they sometimes encounter a very beautiful and provocative woman, who turns out to be the Bécha de Tsanterré, transforming into a large black cow that frightens them, making them flee.

This entity causes cows to lose their milk, ties their tails in knots, steals objects, and frightens people, making the place undesirable for farmers.

Therefore, Jean-Victor and Marie-Reine decided to sell and the only buyer who came forward was the wealthy Joseph-Auguste-Melquir Duc, known locally as Monseigneur Duc and bishop of the Diocese of Aosta.

Thanks to the stories of the Bécha, perhaps cleverly orchestrated and spread, the bishop acquires the property for just over 6000 lire, a bargain price. This includes two alpine pastures, one called Champterré dessus and the other Champterré dessous.

Victor also agrees to pay off the mortgage on the property, in his and his brother Joseph-Séraphin's name.

It is said that, thanks to exorcisms, the Bishop manages to drive the malevolent spirit away from his properties, which subsequently regain their value.

On January 22, 1908, Chevalier Louis-Léon Lanier purchased the pasture from Monseigneur Duc for 24,000 liras, three times the amount paid by the bishop twenty-three years earlier.
