An ‘ephemeral lake’ appeared on the Mont Blanc massif due to warm record temperatures. The phenomenon, witnessed by a guide of the Società Guide Alpine Courmayeur has been reported by the “Montagna Sicura” foundation about the repercussions of the hot temperatures of these days. The training is near the Rochefort group.

The canicular temperatures of these days have shattered the primates of heat in the valley floor, but their effects in altitude still worry those who deal with climate. On the Mont Blanc, due to the effect of a zero thermal that reached a height of four thousand meters, in addition to having created the sporadic conditions for which at least 150 paragliders managed to land on the summit the other day, a lake was formed in recent hours due to of the rapid melting of snow .
Technically speaking, we are seeing an “ephemeral lake”. The “Montagna Sicura” foundation reports this on its Facebook profile , sharing a photograph of the guide of Courmayeur Gianluca Marra (author of a video), which reproduces the unusual phenomenon, testimony to the “many repercussions on the high mountains” of the “Record temperatures these days” .
In the post, the foundation remembers that it is “the same place” (in the Rochefort group, whose most significant peak is the Dente del Gigante) ” in which it had already been observed in 2016 , when our technicians carried out an inspection of land that had not highlighted any problems “. An effect certainly suggestive from the point of view of landscape, but which can only give to reflect on the climatic evolution.
