View from Mont de la Saxe across the Val Ferret to (from left to right) Dent du Géant (4013 m), Planpincieux Glacier, Whymper Glacier, and Grandes Jorasses (4208 m). The tongue of Planpincieux Glacier shows periods of accelerated motion, resulting in instability and, consequently, the occurrence of ice avalanches. Whereas most of these avalanches are small and do not represent a hazard for populated areas or infrastructure, there is a certain possibility of large, far-reaching events. Temporary evacuations have been necessary in the past, based on glacier monitoring data.
