Scialet des Blaches

The cavity begins with a pretty 14-metre-deep shaft, surrounded by boxwood, mossy as desired. One lands on a scree cone that divides the cavity in two.

To the west, two small decorated chambers lie on the right flank of the gallery; one of them reaches, through a narrow passage, a low chamber located at -26 metres. In this chamber, a small 5-metre shaft, narrow at its start, opens onto a short clay gallery that continues via a 4-metre step: this is the bottom, no current is perceptible any longer; we are at -34 metres.

At the bottom of the chamber, one descends through a scree slope; a short well-decorated gallery begins just above a narrow passage. At the foot of this narrow passage, a gallery overlooks a pretty, heavily decorated chamber. Two small, heavily decorated galleries to the north of the chamber join together. A short clay gallery leads to a small chamber whose bottom, filled in by clay, lies at -35 metres.

Access to the low chamber located at -26 metres is easier via the passage cleared at the foot of the scree cone. At the bottom of the chamber, one descends through a scree slope (two passages have been cleared). The continuation lies at the foot of the step where one arrives in the chamber, through a narrow passage, followed by a crawlway that remains severe.
