Description

Morphology

The slide entrance gives access to a sequence of pits and narrow passages oriented along the main joint. At about -70 the cave forks: the <grey branch> leads, with a sequence of small pits and a toboggan, to the old bottom (-106), while the <pink branch> leads to a P25 with difficult access, followed by a wide sub-horizontal branch that morphologically is a crossing point with other arrivals not yet explored. Along the final gallery a barely visible toboggan leads to a further deepening and to the current bottom (about -140), stopped at a narrow passage with strong airflow, currently being dug open.

History

Exploration began more than 10 years ago, with extensive digging and safety works. The exploration, suspended for some years, has recently been resumed.
