Cavity developed along a large vertical fracture, with an entrance overlooking a fractioned P 12 and progression down to -95 m.
Descrizione
Morfologia
The entrance overlooks a fractioned P 12. On the north side, a fissure descends to -17 m. Opposite, a narrow descending zone via an R 7 and an R 5 reaches a loose, rubble-strewn ledge at -26 m. It overlooks a large Faille (humorously named « Grande Faille de Costebougnafle »), vertical, about thirty metres long and 3 m at most. The ends of the Faille were poorly seen but appear to pinch. The floor descends steeply in a narrow fissure, then the width increases (2 m) to reach the terminal chamber cluttered with large blocks at -95 m. Above, a 12-metre chimney has not been climbed.
Progressione
a first vertical of 38 m in three sections lands on a loose, rubble-strewn ledge (-64 m), followed by a new vertical of 18 m in two sections that reaches -82 m. Possibilities of continuation are made delicate because it would be necessary to dig in the blocks.
Altri dettagli
Grey Limestones with pink spots of the Givetian. Cavity dug along a large vertical fracture nearly 100 m deep and of NW/SE direction.
