Bulky and stocky pyramid shaped mountain on the boundary between Italy and France, situated on the ridge between the "Col Pierre Joseh (3.478m)" and the "Col Savoie (3.491m)", almost in the middle between Aiguille de Leschaux and Aiguille de Triolet. It doesn’t look especially sharp from any sides, if compared to the elegant neighbours. It overhangs the glacier of Triolet with a huge buttress that divides the Italian side in 2 parts: the eastern with middle inclination and snow slopes mixed to broken rocks; while the southern side is steeper and rocky. On the French side it has two walls: one is orientated to south-west that overhangs the glacier "Pierre Joseph" and plowed from two snowy gorges; the other more imposing and severe is orientated to north-west and stand above the glacier of Talèfre and carved from numerous ice couloirs. The summit is composed from a rocky crest long 60m that connects two different peaks: NE (3.730m) which is the highest point and, SW (3.726m). The one on SW despite is the lowest, is topographically the most important because is the begin of the crest that divides the basins Leschaux and Talèfre. The structure is composed mainly from rock of low quality especially on the Italian side, and it is commonly climbed more for the spacious panorama that for climb interest. Anyway it’s rarely climbed. Another interesting summits on its west ridge are also the "Petit Aiguille de Talèfre (3.615m)" and the "Aiguilles Pierre Joseph (3.472m, 3.414m)"
