The Decorps-Perroux Route on la Tour Ronde. The solid line represents the normal route. The dotted line at the base of the route represents the route I took during the lean conditions pictured. The normal route finishes on the left hand side of the North Face from where the SE Ridge can be descended. The dotted line at the top of the route represents an alternative finish to the right of the North Face from where the Gervasutti Couloir can be abseiled in to and down-climbed.
