a cavity with a promising porch and a strong draft, whose progression was blocked by a sump before the downstream terminal sump was passed in 2017.
Description
Morphology
The cavity opens with a beautiful porch of promising appearance. The base of the sixteen-metre entrance pit is occupied by a snowfield. One must still descend a pit of eight metres to find the start of a meander. After a final pit of seven metres, progression is stopped by a small sump.
Hydrology
a draft is very noticeable in the cavity. The draft seems to come from an impassable meander corresponding to an upstream. In 2017, the downstream terminal temporary sump was passed.
Progression
The hope of a fine discovery was unfortunately short-lived, since after a final pit of seven metres, progression is stopped by a small sump. In 2017, the downstream terminal temporary sump was passed: a series of pits and meanders follows one after another down to -115 (see links to new 2017 surveys in the "Comments" box below).
