It stands on a ridge separating the Entrèves glacier from the Brenva glacier, yet is somewhat overshadowed by its larger neighbours, such as the Aiguille Blanche and the Aiguille Noire de Peuterey. Nevertheless, it is a distinctive peak, offering a number of very challenging climbs, especially on its east face which consists of vertical granite flakes and cracks. On its northern side stands a distinctive, slender rock pinnacle about 60 metres high, known as the Père Eternel.
