Mont Granier
454 caves have been identified over an area of 2.8 km2, and form two networks under this small area. To the north, the trou des Auges, ressaut de 108 m, trou des Filous, grotte Arva, and Cuvée des Ours connect with the Granier system, located in the center of the plateau, to form a 55.725 km network over a depth of 635 meters. The latter consists of the Gros trou Bib, trou des Panaches, gouffre des Myriades, Étoile du Berger, trou Lilou and trou Mathieu for its main cavities. To the south, the system Balme à Collomb-grotte des Pincherins of 8,336 metres (27,349 ft) for 283 metres (928 ft) of elevation gain, now well known for its cave bear deposit has to date not been connected to the Granier system. On November 13, 1988, cavers Pierre Guichebaron and Marc Papet discovered an extension to the Balme à Collomb cave on the west side of the mountain at an altitude of 5,577 feet (1,700 meters) that contained the skeletons of over 1,000 cave bears that date between 24,000 and 45,000 years. The current Granier massif is a remnant of a previously larger plateau reduced by erosion.
