La Tanne Georges Cher opens with a fault and continues through a gallery to the Mercier shaft, then through low passages and meanders interspersed with small pits.
Descrizione
Morfologia
The entrance consists of a fault, followed by a gallery reaching a good-sized pit (puits Mercier). The cavity then consists of low passages, short meanders interspersed with small pits. A narrow crawlway opens onto this network. The CCDF chamber is vast and chaotic.
Progressione
It is advisable to follow the 1952 network, which seems to be the most pleasant to travel. The cavity is properly rigged up to the CCDF chamber; beyond that, the rigging is unsatisfactory, especially the last pit giving access to the Perche chamber, which needs to be fully re-rigged.
Rigging of the cavity:
Entrance pit: C30 - AN (tree) + 2as + 2S
Puits Mercier: C30 - 2S + 2S
Ressaut chamber: C8 - 2S + 1as + 1S
Entrance pit of the 1952 network: C12 - 2S + 2S
Puits du 14 juillet: C21 - 1AN + 3S
Downstream sector of the CCDF chamber: C10 - 1 AN
Upstream step accessing the salle du Perche: C15 - 2S + 1S + 1dev on AN + 1dev on S (to be partially re-rigged)
Salle du Perche (P9): to be re-rigged.
