Area del Colle San Carlo (Area del Colle d'Arpy), Morgex, Valle d'Aosta, Italia
Colle San Carlo (45°44'33" N, 6°59'28" E), also known as Col Saint-Charles or Col d'Arpy, is a pass at 1951 m a.s.l., located in the vicinity of Tête d'Arpy, connecting Morgex and the Arpy Valley to La Thuile (Dora di Verney Valley).
In the Colle San Carlo area the tectonic contact between the "Zone Houillère" and the Versoyen units is marked by a large (ca. 100 m) belt of gypsum, which enabled the tectonic displacement. The large Triassic gypsum outcrop, located at Plan de Buillet (1980 m) in the municipal territories of Morgex and La Thuile, is characterised by the presence of numerous dolines and shinkholes above the forest track leading to Lac d'Arpy.
The so-called Colle San Carlo anatase occurrence is located to the north of Colle San Carlo, in the municipal territory of Morgex, inside the dense conifer forest that characterises the left side of the lower Dora di Verney Valley. This occurrence is usually indicated by the mineral collectors as "Colle San Carlo, La Thuile" or just as "La Thuile", because it is generally reached from La Thuile, following the road SR 39 towards Colle San Carlo until the parking area next to the road which leads to the village of Petosan. The hike from the parking area to the mineral occurrence, via Petosan, takes about 50-60 minutes.
