Crête Sèche (Mont Blanc massif)

Crête Sèche is a rocky arête (narrow ridge) located in the Mont Blanc massif, within the French Alps. It is situated on the Italian side of the mountain range, overlooking the Val Veny. The Crête Sèche forms a distinctive feature on the southeastern flank of the Aiguille Noire de Peuterey, a prominent peak known for its challenging climbing routes.

The ridge is primarily composed of granite and is characterized by steep, exposed sections requiring technical climbing skills. It presents a relatively long and demanding alpine traverse, typically undertaken by experienced mountaineers.

Access to the Crête Sèche is usually achieved via approaches from the Val Veny, involving glacier travel and scrambling over rocky terrain. The ridge itself offers views of the surrounding peaks, including the Aiguille Blanche de Peuterey, Mont Blanc, and the Grandes Jorasses.

Climbing the Crête Sèche is heavily dependent on weather conditions and requires appropriate equipment, including ropes, ice axes, crampons, and protection gear. It is considered a significant alpine undertaking, and should only be attempted by those with considerable experience in mountaineering and rock climbing.
