On a boulder about 70m East of Voile Solaire. Climb the left arete to take the large pocket right hand and exit on the right. NB : unknown problem rediscovered by Jason Kester.
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.
