The Fenêtre de Champorcher (French pron. AFI: [fənɛtʁ də ʃɑ̃pɔʁʃe]; also known simply as col Fenêtre, which means window hill in French) (2,827 m a.s.l.) is an Alpine pass in the Graian Alps which joins the Champorcher valley and the valley of Cogne. The hill opens between Bec Costazza and Torre Ponton. From the side of Champorcher la Finestra is located upstream of Lake Misérin and at the head of the valley; from the Cogne side it is found at the head of the Urtier valley (secondary valley of the Cogne valley). From the window the Gran Paradiso national park begins on the Cogne side and on the one towards Champorcher the Mont Avic natural park.[1] According to the SOIUSA orographic classification, the hill separates two of the supergroups that make up the Gran Paradiso Alps, the Emilius-Tersiva Chain (north of the hill) from the Rosa dei Banchi Group (south).[2] It is located along the route of the Alta via della Valle d'Aosta n. 2. The hill, as well as the path, is crossed by the high-voltage power line that transported the electricity produced by the French Superphenix nuclear reactor to Italy.[3]
