The Glacière of Autrans

The Autrans cooler is a cavity where snow accumulates in the winter and persists for much of the year. It has been traversed by cave explorers for a long time, since 1936 the speleo club of Paris arrives at the depth of -45 meters and it is in 1988 that the siphon terminal is explored in diving to -221 meters. Its karst network develops thanks to an enormous fault. Its resurgence is the Goule Noire (in the gorges of the bourne) distant of 18,5 km!
