Bòfia del Tec

A 2x1 metre mouth that gives access to a gallery partially flooded in the first metres and which then rises slightly; at 35 metres from the entrance, a narrow passage between concretions allows continuation, finding a first partially flooded section and further on a low-ceilinged section with a pothole full of water must be overcome. The next section rises a little and is found dry, but immediately a sloping plane is found again and the gallery descends gently, with the floor covered by countless gours. When it becomes horizontal again, the ceiling lowers and the section gains a little width for about seventy metres, until reaching a small chamber that is usually covered with water. Here the main gallery ends, but a few metres before, above a narrow passage between blocks that sometimes sumps, we find an ascending flat-out passage about 5 metres long by 1.50 metres wide and depending on the season, a small water inflow descends. It keeps these dimensions almost throughout its entire route, ending in a tiny little room at +25 metres of height from its start. Through a series of openings located in the left wall, one accesses a new descending gallery and of chaotic appearance in a first section, due to the presence of large fallen blocks; further on one reaches a chamber of medium dimensions, where at mid-height we find a joint through which one can climb between ledges and small little rooms until finally reaching +30 metres of height, during the whole ascent we are accompanied by a large amount of mud. Back in the gallery, a drop of -3 metres must be overcome above an erosion pothole. From here one enters the final section of the gallery, in a descending direction and the floor full of pebbles, reaching a sumping vault that prevents continuation. The vertical range of the cavity is 46 metres (+17/-29).
