Geography

The valley is part of the hydrographic basin of the Dora Baltea, and has a U-Shape. Just before Cogne, four minor valleys gather to form the Cogne valley: the Valnontey, leading to the Gran Paradiso, the Grauson Valley, leading to the Grauson peak, and, eastwards, the Urtier Valley and the Valeille. All the streams from these valleys flow into the Grand Eyvia, which flows into the Dora Baltea near Aymavilles.
