Descrizione
Morfologia
A first pit with a drop of 3.50 metres connects with a descending gallery 7 metres long, which is followed by another shorter and less steep one; then the descent stabilises and one enters a zone crossed by other galleries at different levels, creating a fairly complex closed circuit. Continuing along the main gallery, three small pits of 3.50 and 4.50 metres respectively follow one another; at the bottom of the last one the maximum depth is reached. The cavity continues through a narrow crawlway, full of mud and with a siphoning appearance, and then takes a notable ascent until reaching the -18 level, where the cavity ends. In this final sector some small side galleries and a final chamber on the upper level develop.
Storia
Discovered in 1968 by two relatives of the well-known Girona industrialist Torras Hostench, hence its name.
On 3 December 1972 it is explored and surveyed by the Centre Excursionista Empordanès de Figueres.
In 1978 La SIRE-UEC de Sants explores and surveys it again.
In 1986, while reforestation work was being carried out with a subsoiling machine, they moved the rocks that formed the entrance and the cavity was covered with the same rocks.
Between May and June 2008, members of the SIE-CEA unblock the cavity, placing a wooden pallet at the entrance to prevent falls.
