23 moves rallongation of Spéléologue, on the boulder of La Caverne (red n°24), underneath the plateau, in the Eastern part of the sector. Start in the cave with the neck of a big "fish head", take on the big holds of the "stalactite", climb the roof and exit in La Caverne (red n°24).
NB: this problem was opened without the part of the cave opposite the 'fish mouth' (see drawing) but a non eliminant version is probably nicer.
Update (August 2019) : a hold has broken at the exit off but the problem is still possible with the same grade.
