Summary: After the terrible descent from Col de Voza, I sleep in Les Houches. The next morning is a long valley walk then up Col de Balme. A gnarly high level route under the Glacier de Trient leads to the start of the last climb, a steep one over Fenetre de Arpette. The ugly drop into Champex Lac marks the end of the trip and the beginning of a 36 hour trip back to Colorado.
