We have traced from the Grand Montets and attachment reached in 90 minutes. Unfortunately for us it lasted very little. At the second pitch a small avalanche pulled us all down except one. 80m flight with helicopter rescue and recovery. Colouir still load of snow and very unstable with frequent discharges during the day. If someone goes over we have left many climbing materials and one camera, we would appreciate if you would send email. We thank immensely the French gendarmerie who make us quickly and professionally rescue!
