Super few days in beautiful Drôme celebrating International Commission on Stratigraphy IUGS Durham Earth Science achievements. Not one but two Golden Spike dedications…the Albian and Hauterivian stages of the Cretaceous. Thanks to everyone involve especially the communities of Arnayon and La Charce. /2
