Gouffre Stella Marq

At the bottom of a 3.5-metre doline, on the west side, a small crawlway between blocks gives access to a 15-metre shaft. This leads to a scree slope inclined at 45°. Downwards, the scree slope leads to a small step overlooking the second 15-metre shaft, circular and 2 metres in diameter. At its bottom opens a small meander, narrow and low, whose floor is cluttered with blocks. After ten metres of progression, one emerges into a chamber where one must descend by climbing. The meander continues beyond, higher but narrower, and gives access to a 56-metre pit with a substantial ledge at -10 metres. This pit marks the end of the explorable part of the "Stella Marco".

The meander is semi-active.

The upstream part of the scree slope continues beyond the first shaft for some metres and ends in a cul-de-sac at the start of an ascending shaft, choked with blocks.
