Preparation of the sampling equipment at the Jardin de Talèfre, a rocky outcrop on the Talèfre glacier in the Mont-Blanc massif in France in September 2016. The aim of this mission to collect samples from surfaces polished by glaciers in the Mont-Blanc massif was to determine how their position had changed since the end of the last great glaciation, approximately 10,000 years ago. The purpose was to ascertain whether these glaciers had ever been smaller than they are at present, when they are…
