FN 13

FN 11: the entrance is A large collapse inside A blind valley, partly masked by big blocks. To the East, A 7 m shaft/joint was descended by going around A big block used as an anchor on the right; its floor, perpendicular, is earthy. A passage heading North is soon blocked; to the South, A fissure descends, quickly impassable; on the West side, A fissure choked with blocks coincides with A neighbouring cavity, FN 13. Opposite, A pretty, well-rounded P7 ends on A clogged joint (earth, animal bones: roe deer...).

FN 14: the entrance shaft, 2 m in diameter, is in two parts cut by an earthy ledge at -7; behind this ledge, rocky overhangs overlook an E/W joint, 1.2 m wide and 7 long; on the East side, A small parallel shaft can be reached by passing behind A rocky ridge. A fissure perpendicular to the joint, oriented North, descends A few metres (by sound).

FN 13: the entrance, along A rocky bar, is choked with blocks; the descent is made in A volume that would be large without the wedged blocks that force A crooked route. One arrives on an earthy flat. To the East, A short inclined plane leads to the P 9 (cf FN 14). To the West, A narrow descending passage between smooth walls leads into FN 11.

East of the flat in FN 13, A short inclined plane leads to the P 9 (cf FN 14), with remains of corroded stalagmitic flows.

FN 11: one descends along the West wall to arrive on scree. To the East, A 7 m shaft/joint is descended by going around A big block used as an anchor on the right.

FN 14: to the West, the joint leads, after A left-hand bend, to the bottom of A 9 m chimney, climbed on the day of discovery, and which turned out to be the P 9 of FN 13.

FN 13: to the West, A narrow descending passage between smooth walls leads into FN 11.

FN 14: air comes out fairly distinctly from the North-oriented fissure (possible junction with FN 15, very close?).
