This sector is constituted of a sole boulder for the moment (September 2016).
Access: from the parking lot of La Plaine Verte, take La Route de la Mort to the South-East towards Le Calice, then La Route de la Grande Vallée to the East. 50m before the crossing with La Route de Fontainebleau à Montigny, follow a small path down the slope to the North-West for 100m up to the boulder.
