Becca d'Aver, Mountain summit in Valle d'Aosta, Italy.

Becca d'Aver is a 2,469 m mountain in the Pennine Alps of Valle d'Aosta, standing between the Valtournenche and the Vallone di Saint-Barthélemy. Three ridges run down from the summit, separating the Valtournenche from the Saint-Barthélemy valley and from the central Dora Baltea valley. The summit looks out on the Matterhorn, Monte Rosa and the Rutor.

The sources record no wartime role for Becca d'Aver; its documented history is cartographic and mountaineering. It appears in Italian alpine literature as a 2,469 m summit of the Weisshorn and Matterhorn Alps, on the watershed between Valtournenche and the Vallone di Saint-Barthélemy. Its three ridges also divide those valleys from the central Dora Baltea valley, a position that made it a natural survey point above the routes from Lozon, Chantorné and Praz.

The name Aver comes from the local dialect and appears in the French form Pic d'Aver. The summit stands on the ridge between the Valtournenche and the Vallone di Saint-Barthélemy, and the three crests running down from it mark the divide between these valleys and the central Dora Baltea valley. Walkers reach the top from the hamlets of Lozon, Chantorné or Praz.

The summit requires approximately 800 meters of positive elevation gain from the starting point and is best accessed between June and September when trails remain snow-free.

The summit stands at 2,469 m, while the Cebuano source gives 2,468 m; it rises about 281 m above the surrounding terrain, and the Becca di Luseney lies 8.5 km to the north. Three ridges descend from the top, separating the Valtournenche from the Vallone di Saint-Barthélemy and the central Dora Baltea valley.
