Earth sciences

Geology & landscape

The trail climbs the southern Gran Paradiso slope on Penninic calcschists and micaschists with augen gneiss outcrops of the Austroalpine basement above 2200 m. Lauson pastures develop on Würmian glacial deposits with rebuilt moraines and lacustrine sediments. Lake Djouan occupies a cirque carved by the Würm glacier with terminal moraines and proglacial deposits. Rocks around the lake show glacial striations and meltwater potholes. Gran Paradiso granite (Dora-Maira unit) outcrops appear near Becca di Moncorvé. Periglacial scree deposits indicate instability on slopes above 2400 m.

History & culture

Valnontey is the southern gateway to Gran Paradiso National Park, established in 1922. The lake is a classic ibex-watching destination, symbol of the park.
