Description of the route

Day one
From Glassier take the clear mule track for By that winds upwards until you come to a small church. Turn left towards a small dam; cross its coping and you will pick up the trail of a country road. After passing it, carry on the slope that heads up to Alpe Porchère. Pass by the mountain pasture furthest upstream - Tsa Porchère - and continue along the path that turns to the left along a water duct. A little further on you will come into a valley that heads up as far as the grassy hump where you will find the Savoie bivouac.
Day two
From the bivouac, follow a pathway that leads to the valley of the Valsorey Pass. Look for traces of the path that rises up between the rocks that take you under the last slope defending the pass. Come at it from the left and you will come to a pass with a crossing to the right. Carry on to the left on a clear rocky ridge following the stone figures that lead to Mont Cordine 3,323m. From the peak, come down towards a clear carving, Col de Chamois, that can be overcome with the aid of a fixed rope; head back up a stretch of the ridge until you come to the Valsorey glacier, leaving the Dents du Velan on the left and heading back up the 2 clear snowy humps that lead to the terminal dome.
