Descrizione
Morfologia
The system develops within a small outcrop of gypsum intercalated in the surrounding limestones. The total route is 1315 metres and the height difference is 30 metres. The speleometry given by the authors has been respected, but we do not know what criteria were adopted in order to place the 0 level at the lowest point of the system.
Idrologia
Through the system flow placidly the waters captured at various points, finally draining through a point not located in the Borró river. Occasionally the Bora de Can Bellús acts as an overflow. From the Bora de Can Bellús a stretch of the cavity can be visited without any difficulty. The gallery leads us to a wide chamber; once through it and following the lower part of the gallery we reach the point where two rivers converge. Along the left one, temporary, a hidden and narrow passage situated above the plunge pool leads us towards the Bora 5; after passing the parallel galleries we find a good stretch occupied by water, which does not facilitate exploration and sometimes prevents it. Back at the starting point, the right-hand river, perennial, leads us to the sector with the greatest length. This first stretch is wide but with a low ceiling, with many chances of getting wet on exiting through the Bora no. 2.
Progressione
From the Bora Gran or no. 4, situated at the bottom of the Torrent, through a beautiful meander we can access the different conduits that converge at the survey point of section 32 and from there continue along the different conduits that lead to the Bora no. 11. From here, from the main gallery a narrow conduit leaves to the left and in a southerly direction which will take us to the Bores no. 6 and 6 bis, and turning towards the north-east we will reach the Bores no. 7 and 7 bis. From the Bora 11 the gallery heads towards the Bora no. 2 and the Bora de Can Bellús.
Storia
Explored by the GE Badalona and collaborators from other organisations during the years 1993 and 1994. Previously the sector between the Bora de Can Bellús and the Bora no. 2 had already been explored, as well as a stretch of the left-hand river at the confluence, since painted arrows were found pointing towards the exit, although it is not known who the explorers were. The synonyms that appear in the system correspond only to the mouth of the Bora de Can Bellús.
