Meeting the great fauna of the Vanoise
Refuge de Rosuel
Let's go snowshoeing for half a day to discover the glacial history of a valley in the Vanoise National Park and the living world that has gradually colonized it over the last 20,000 years.
Starting from the Pont Baudin (Nordic Center of Peisey-Nancroix), we progressively go up the Rosuel valley off the beaten track in the direction of the Gurraz mountains to better understand the glacial history of this valley and the conquest of the living world that has taken place since the beginning of their retreat 20 000 years ago. The vast snowfields punctuated by a few melezins that we cross against the backdrop of the ice cascades and the glacial front of the Platières give this valley an atmosphere of the Great North.
In the mountains, there is no such thing as chance, whether it belongs to the animal or plant kingdom, each living being has developed adaptations to survive the harshness of winter in the mountains. Up close, we will follow the tracks used by foxes and hares; from a distance, so as not to disturb them, we will observe the patient work of ibexes and chamois to feed themselves. And man, in this landscape? He also knew how to deal with the slope and the marked seasons. We will explore how he has adapted his rhythm and activities to the mountain and the adaptations he will still have to make in the face of climate change.
