A cavity whose entrance, 0.5 m by 0.5 m, opens at ground level, with several small steps, constrictions and Un small parallel network.
Descrizione
Morfologia
The entrance (0.5 m x 0.5 m) opens at ground level in the earth. The bottom of the cavity consists of A narrow joint. At mid-height there is Un large ledge where A cleared constriction leads to Un small parallel network ending at another constriction (not passed). The bottom of the cavity is choked by the various collapses produced during the opening.
The dip of the strata (35 to 40 degrees) is the same as for all the cavities in the sector located on the same slope of Costebelle.
Progressione
Un small step leads to Un ledge where there is A cleared constriction (1 shot). Another series of small steps leads to the bottom of the cavity.
