An important secondary peak of the Aiguille Verte (4122m) with an impressive North face (from side of Nant Blanc glacier). The summit is rarely climbed (serious proposition, objective dangers, difficult mixed climbing and serac barrier on N face), the easiest descent is to continue along Sans Nom Ridge and over summit of the Aiguille Verte. The North face of the Aiguille Sans Nom offers some of the best mixed climbing in the range.
