Central problem on La Roche Acléaude, to the sourth-east of the main sector, on the ridge. Crouching start with the edges to the right and exit above.
NB: This problem has been opened in 2015 and we decided at the time not to publish about it because its ascent required the destruction of an old bivouac. We do not know how or why the old bivouac collapsed. In april 2017 someone damaged many holds. We ask everyone to leave existing constructions and boulders intact.
