Aven du Lapiaz n°3

The cavity begins with the fairly narrow P15. At the bottom, Un very short sloping crawlway opens directly onto the P40. A first narrow length (with 2 deviations), then the shaft becomes vast and concretion-covered. One reaches the bottom of the P40 onto a slide. One then follows a rugged gallery. Almost before the bottom and on the right, a large (and heavy) calcite plate is placed to mask and protect what follows. The passage, once cleared, leads to Un passage ascending between blocks and concretions (easy climbing of about ten metres) which ends at an immense horizontal fault with a calcified floor.

The horizontal fault is very richly concretion-covered, with lines of white concretions and very fragile soda straws.

Equipment is no longer necessary for what follows after the bottom of the P40. Take care to follow the few routes marked by the passages (but unfortunately not waymarked) and do not stray from them so as not to soil and break! Remember to close the protected passage properly when leaving!!!
