M2

a narrow down-climb between fluted walls leads into a small decorated chamber 2 m x 2.5 m; the floor is broken by a fine 27 m pit, of variable diameter (from 1 m to 2.5 m), with a ledge of blocks wedged in the flutes 12 metres lower. 4 metres below this ledge, a window is a view onto a short forced conduit parallel to the wall, oriented east/west, blocked by speleothems. The bottom of the shaft is a stony slope that narrows into the start of a meander at the low point. Another parallel niche, behind, descends a little less deep.

The small entrance chamber is decorated; the forced conduit parallel to the wall is blocked by speleothems. Lower down, a small chamber is adorned with sharp blades, and the bottom is decorated; an impenetrable passage, between massive flows, was filled with water at the time of exploration.

a dig allowed the constriction to be passed and an 8-metre down-climb to be descended which, widening, leads to a small chamber adorned with sharp blades. -48 is reached by descending on the left between blades surmounted by a small chimney.
