 In 1787, on the second of August, Jean-Joseph Vidal, an astronomer from Mirepoix, and the chemist Henri Reboul from Toulouse, who was studying the snowmass in the Pyrenees, made the first recorded ascent.They gave their names to the rocky ridge which extends from the crest of Turon towards Cap-de-Long Lake.The peak is easily accessible from Barèges, going past the alpine "hut" of "Refuge de la Glère", by Lake Glère.
