A cavity formed by an accumulation of large blocks yielding passages that are more or less passable, with rock chutes and a low point at -11 m.
Description
Morphology
A cavity difficult to describe because it is a sort of accumulation of large blocks between which more or less passable passages have been cleared. To the east, a rock chute at -7 (-12 on the survey plan). To the west, a passage between large blocks leads to several continuations that all end either in passages that are too narrow or in rock chutes. Low point at -11 m (-16 on the survey plan), on the mountain side. On the north side, a narrow ventilated passage (-7 or -12 on the survey plan) must connect with the very nearby Trauc del Buc (5 metres), in which there is also air.
Progression
After the cleared fissure at the entrance, one steps into a widening, then a short climb-down leads into a larger volume.
Other details
White limestones of the Emsian (Devonian).
