On the boulder with Des Racines et des Aigles. Standing start to the right of the overhang with the right foot at the bottom right of the crack, right hand on a crimp and left hand in the central big hold, traverse to the left to reach a vertical crack then traverse to the right and mantle up at the top as for Les Racines de l'Enfer.
NB: the sitstart remains to be done but the holds are fragile.
