Cavity under exploration in 2009, with a dug-out squeeze leading to a junction, a main gallery in a forced conduit and a 3-metre climb to a ventilated gallery.
Description
Morphology
a low, crumbling gallery leads to a dug-out squeeze. The squeeze is short and you straighten up very quickly in a nice volume, forming a junction.
The main gallery is a fine forced conduit that very quickly gains slope. Opposite, the gallery continues for about fifty metres, increasingly choked by dry clay. This gallery descends towards les Avoudrues.
a 3-metre climb leads to a small gallery with a draught, still to be explored.
The entrance leads to a short descending gallery 5 metres long that ends at the dug-out crawlway. This short crawlway leads to a large forced conduit 3 m x 4 m that descends steeply. Above the crawlway, a ventilated branch has not been explored.
The forced conduit crosses a choked 15-metre shaft and, after 2 steps of 5 metres and 3 metres, loses its slope and therefore gains in choking. It ends up completely obstructed.
Hydrology
The crawlway was blowing on opening, but with no draught during the first survey and the survey (because of outside temperatures?). No draught during the exploration (2014).
Progression
Equipment is needed to cross a blind shaft.
