A cavity beginning with a 4 m x 4 m porch, followed by a horizontal gallery and a passage rising to +10, with two chimneys and a clay plug at +12m.
Description
Morphology
The cavity begins with a fine 4 m x 4 m porch followed by a horizontal gallery with a stony floor. After 15 meters, the ceiling lowers slightly then rises again, and the passage, of fine dimensions, climbs more and more steeply up to +10 where a flat step is reached.
On the left, a meander inlet then a 4-meter climb through blocks leads to the foot of two chimneys: one to the north, wide and with speleothems, is blocked at +23m; the other to the south, narrower and meandering, stops at +24m.
The main passage continues east while rising. One passes a pit adjoining an old stalagmitic mass, then enters a much more clayey, rather descending part that ends at a clay plug at +12m.
