Under the summit of the Pinet there is an important underground network, the Pinet - Brouillard system of 11,175 meters of development for 507 meters deep. This system is not connected to the Alpe network, although nearby. Nearby opens the grand Glacier network of 371 m of elevation gain for a length of 2,926 meters well known for its ice river.[1]
