Grotte de la Cigale

The cavity develops at the intersection of two fractures: SSE/NNW (3/4 of the cave) and N/S. It is excavated in Upper Georgian sandstone-limestone alternations.

a succession of descending passages between dubious blocks, separated by a few constrictions (Boîte à lettres, le Délice d'André), leads to -61 m in a horizontal gallery of 35 m ending at a narrow chimney. a few metres before, Un conduit rising at 45° ends at Un unstable scree slope at -45 m. At the start of the gallery, Un vast shaft rising at least 25 metres breaks through the ceiling. To the north, Un other rising shaft dominates the horizontal gallery; at its top, Un ventilated tributary has been ascended to -4 m (very severe squeeze). Un descending passage in the blocks at the start of the gallery reaches a boulder-filled chamber at -75 m. To the south, a short gallery is blocked by a fissure. On the left side and at the top of Un P10 (rotten climb), Un corridor leads into a boulder-filled chamber blocked at -52 m. To the west of the chamber, Un sloping scree slope followed by a series of muddy squeezes (onion squeeze) leads into a small chamber.

a narrow fissure located behind two large blocks widens Un little further on (ascent in blocks leading into the terminal scree slope of the galerie du Bouquet). At -82 m, Un tributary of 40 metres has been ascended to -38 m. At the start, chimneys lead to an upper chamber also accessible via the galerie du Bouquet. a descending passage between large blocks allows reaching the terminal sump at -91 m.

Going back up the fissure above the blocks, one reaches the galerie du Bouquet after a few viscous oppositions. To the south, it is blocked by Un large scree slope ascended to -25 m. To the north, it pinches out after 30 metres. In the ceiling, two inlets have been ascended over several tens of metres.

No perennial circulation.
