Lago Blu (Lac Bleu), Catena della Gobba di Rollin-Rocca di Verra - area del Lago Blu (Chaîne de la Bosse de Rollin-Rocca di Verra - région du Lac Bleu), Champoluc, Ayas, Val d'Ayas, Valle d'Aosta (Vallée d'Aoste), Italia
Lago Blu (aka Lac Bleu, Lac de Verra, Lac Bleu de Verraz or Lac Bleu de Veraz) is a small moraine-dammed lake situated at 2215 m a.s.l. between the east slope of Rocca di Verra and the western lateral moraine of Grande Ghiacciaio di Verra (aka Ghiacciaio Grande di Verra, Ghiacciaio di Verra Grande, Grand Glacier de Verra, Grand Glacier de Verraz, or Grand Glacier de Véraz). It formed in the second half of the 18th century, when the tongue of the glacier advanced considerably causing the first damming phase of the lake (The glacier front reached the maximum expansion in the period 1819-21 near the bridge over the Verra stream, at the north margin of Pian di Verra Inferiore).
Minerals are found in the rock debris (mainly consisting of serpentinites and subordinate rodingites) forming the screes at the foot of Rocca di Verra and the large western lateral moraine of Grande Ghiacciaio di Verra. In the lake area, rocks of the Monte Rosa nappe (metagranites, gneiss, schists) carried by the glacier from the eastern part of the Verra glacial cirque are occasionally found.
