a cavity whose route leads, through a shored scree slope, a descending passage and a meander, to the P106 rigged in a calcite flow.
Description
Morphology
The entrance of the cavity is a scree slope. You quickly reach a narrow descending passage, then come out in a meander. At the end of the meander there is a 15-metre pit, split once, then a small step. You then reach a small chamber. The P106 pit is descended free-hanging for nearly 100 metres, down to a ledge.
Speleothems
The access to the P106 is at the bottom of the small chamber, in a calcite flow.
Progression
There is no possible hesitation, the passage is shored; you must therefore move gently. The narrow descending passage can be down-climbed, but it is recommended to install a rope to help with the ascent. In the meander, you must stay high. The 15-metre pit, split once, then the small step are descended without a rope, but to climb them it is better to rig them. The access to the P106 is marked. Start rigging at the top of the calcite flow, the pit is just below; at the ledge, you must split the drop to reach the bottom.
