On a boulder about 150m East of Voile Solaire. Start on a stone in the center of the wall, gain the large pocket up and left, then mantle direct, to the right of Tonnerre Volé (direct).
Access
Head South from a point 20m West of the crossing of Route de Barbizon à Fontainebleau and Route de Clair Bois, picking up a small trail heading up the hill. The boulder is just left of this trail after about 100m.
