We reached Pas de la Bosse, 1816 m, SW of the summit of Cornettes de Bise. Here is an important crossroads. Towards the SE you go on Chalet de la Cheneau and further down on Chalets de Chevenne. Towards the W and later SW you go to Chalets de Mens. Towards the NW you go down into the valley of Bise. And towards the E and then NE you ascend the summit of Cornettes de Bise by Saix Rouquin route. August 10th, 2012.
