First sample for Dilan Rech at the Bois des Fournets (Vallée de L’Arve, France). He is starting a Master project at the University of Lausanne about ice-extent reconstruction of the Western alps glaciers using OSL dating. This sample is part of a 10 cm layer of fine sediments forming the Rocailles moraine located 20 km southeast of Geneva. The sediments were sampled using a tube to prevent light contamination. For Dilan, the adventure has just started and he already has a bright smile on his face.
