Interesting shots - nice work getting those big bikes up there, too. I was riding in the same area a lot this summer - did Flaine - Vallee de Sales - Refuge Anterne - Refuge Grenairon - Sixt fer a Cheval - Samoens - Flaine - l'Hameau - Magland in two days this summer, pics here www.pinkbike.com/photo/6966811

Also a great walk from Emosson over to Sixt via Refuge Grenairon
