The glacier d'Ossoue and the peaks Central (left, 3235m) and Zerbillonar (right,3257m) in the climb to Pique Longue. In the middle of both peaks is the Col of Lady Lister, point of entry to glacier from the route of south face. Is a good idea climb this easy peaks after the Pique Longue from the col. 6 september 2003.
