Abstract The Valle d'Aosta (Italy), in spite of its importance between the alpine regions, has very few balances of mass available. The series of Grand Etret (Gran Paradiso Group, Western Alps), even if short, is therefore quite interesting. Since 1999, the mass balance is carried out within the framework of a co-operations agreement between Gran Paradiso National Park and University of Turin. The calculation is based on the direct measure of accumulation and ablation. The mass balance is negative in all year, except the 2000-2001 (+60104 t). The 1999-2007 total balance is negative (-464104 t). The snout's variations are similar in the same period; the retreat of the tongue is 68 m in the last 8 years.
