A network of shafts reaching -345 m, where a stream leads to the Grand Cèdre shaft and to a chaos of blocks.
Descrizione
Morfologia
The network consists of a succession of shafts that can be watered after rain, leading to the DE JOLY chamber at -65. The continuation at the bottom of this chamber can be obstructed by sediment after heavy weather. The descent of the Grand Cèdre shaft is done in free hanging. One lands on a huge chaos of blocks. A continuation in a joint against the wall is being dug open (2010), with a strong draught.
Idrologia
A stream interspersed with a R5 and a P6 leads to the start of the famous Grand Cèdre shaft. The descent of this P146 is sheltered from the stream, which sinks a little before, except in flood.
Progressione
The network descends to -345 m. For the ascent, bring a survival blanket to make a tortoise so as not to get too cold while waiting.
