A cavity that descends through a series of steps and chambers to a 78 m pit, then joins the upstream network of the galerie des Coquillages.
Description
Morphology
The small entrance opens onto a series of steps and chambers up to the top of the first 78 m pit, a magnificent one. At the bottom, a 5 m climb gives access to the following P 39. After descending a P 10, one must traverse a ledge above the last P 10, whose bottom is flooded, to reach the bottom of a very large ascending gallery. In the terminal chamber overlooking this astonishing gallery, a P 20 and passages between the blocks give access to the upstream network: the galerie des Coquillages. This offers pretty phreatic (forced-conduit) scallops. It is interspersed with 3 small pits and can be followed as far as a temporary sump at elevation -180.
