Descrizione
Morfologia
Wide entrance with numerous txoas or grikes inside. A wide pit of about 40 metres is open on vertical bedding, and another wide pit of about 40 metres is oriented along an East-West joint. The cavity continues through a 54-metre pit, following a chain of pits with small ledges that bring the whole to a depth of -180 m; here the joint changes direction to North-South, with a 37-metre vertical drop and formation of a meander at its bottom, continuing through two new pits of 5 metres and 10 metres. The total depth is 225 metres.
Idrologia
The bottoms are occupied by snow at 11 metres and 16 metres. There is an indraft air current in the final narrowness.
