On the big boulder of Le n°1 de la Dalle aux Pigeons (mauve n°28) and Little Big Man. Standing start with the two hands on a sandy sloper as for La Pierre Angulaire, climb the complete arete and exit on its right.
NB: opened around 2010 but roped up because it was too dangerous. First ascent without a rope (since the fall of a tree and the creation of a terrace) by Aubin Salmon and Fabien Chavanneau in 2023.
