Downhill behind you, you will be able to see the lakes of the Aussois dams. The Plan d’Amont is remarkable for its turquoise colour, fed only by the melting snows and clear streams. Downstream, the Vanoise glaciers feed the lake thanks to 19 km of underground tunnels originating from the Doron de Termignon. The water is loaded with glacial “flour”, fine mineral particles torn from the mountains. This is what gives the Plan d’Aval its grey, milky colour.
