Gouffre Jean-Bernard or Réseau Jean Bernard, sometimes known simply as Jean Bernard, is the seventh deepest cave in the world, and the third deepest one in Europe. It is in the Alps in Samoëns, France. The first entrance to the cave was found by the French caving group Groupe Vulcain in 1963.[2] More entrances have been found over the years since, and currently at least thirteen are known. The highest entrance, known as C37, is at 2,333 m (7,654 ft) above sea level.[1] The cave is named after Jean Dupont and Bernard Raffy, two Groupe Vulcain members who died in 1963 in an unrelated expedition in Goule de Foussoubie Cave.[3]
