The cave of Prérouge in Arith, Savoie, resurgence of the waters of the Bange mountain
The Bauges massif contains many underground cavities. There are three main sectors: the Margériaz, the Revard sector and the mountain of Bange-Prépoulain.[1] Under these karsts large underground networks develop in particular the Creux de la Benoite-Litorne-Grotte de Prérouge with a depth of 860 meters for 54 kilometers of development.[2] The Margériaz sector is renowned for the length and difficulty of its meanders, which are particularly difficult to explore.[3]
