Climb

From the Maljasset refuge, traverse the Ubaye (point 1902m) then follow the cross-country ski tracks which lead to the opening of Vallon de Mary. Traverse the torrent (bridge) and continue in the field until a second small dale (road). Go up this road which ends on a flat area (point 2045m). Then go up the Vallon de Mary by skirting this side until the higher Bergeries de Mary (2380m -abri open). Go back to the left bank of the dale and traverse under the Marinet rocks in the direction of the spillway of the Lacs du Marinet (at the foot of Aiguille Large). Pass Lac du Marinet (point 2563m) then to go up the moraines which follow then the Glacier du Marinet until the bergschrund (around 2950m). The corridor makes a "Y", the notch can be done by traversing  the left branch but the right branch climbs slightly higher. Generally climb the corridor on foot, in good snow it is possible to climb it on skis.
