A cavity entirely excavated from a low entrance, once a simple fissure, in order to reach a larger network, without succeeding because of an obstinate boulder choke.
Descrizione
Morfologia
Originally, only the low entrance was known: a tiny fissure exhaling a draught. The whole of the cavity was excavated with a view to reaching a larger network, but an obstinate boulder choke did not allow the hoped-for continuation to be reached. The low entrance begins with a crawlway followed by a narrow ascending step; a slightly more spacious conduit follows and opens into a small chamber cluttered with blocks coming from the surface. At the back on the left, a fissure communicates with the upper entrance. A little before, also on the left, a descending crawlway leads into a tiny rotunda where a high passage leads back onto a very narrow descending fissure. The upper entrance opens onto a pocket in an unstable boulder choke. A passage at the back, between blocks and wall, could continue but would require serious shoring.
Idrologia
The cavity is traversed by a fairly noticeable and constant draught, certainly slowed by the crossing of the boulder choke, which must be substantial.
