Avenc G-5

The entrance is horizontal and follows a succession of small steps between blocks, until reaching an elongated chamber. Two continuations leave this chamber. The first is on the right, after climbing over a block where there is an inclined pit of -6 metres; a gallery of a few metres begins, gaining depth rapidly until it links up with another perpendicular gallery 5 metres long, which leads to a vertical squeeze of -2 metres. This squeeze gives access to the upper part of a gallery perpendicular to the previous one, of little width and descending, which reaches the maximum height of the cavity at -19 metres. Through the second continuation one enters a wide gallery with an inclined section 12 metres long and a floor covered with blocks.
