Narrow fissure in the N260 limestone cliff face, next to the P24, opening to 5 metres deep and continuing along a lateral meander to a debris cone.
Descrizione
Morfologia
The N260 limestone cliff face shows stepped small drops above the dolines at the bottom; the reference fissure opens in one of them, within a set of fissures and a strong joint crossing in the most depressed part of the group, with abundant vegetation and wall mosses. The fracture is very narrow and opens further down to 5 metres deep, with a bed of humus and blocks.
Progressione
After the blocks, one descends 1.5 metres further along a lateral meander of horizontal development that, after 2.5 narrow metres, ends in a debris cone beneath an impassable chimney.
