Siebenhengste-Hohgant-Höhle

The cave was first explored in 1966 by the Club Jurassien, a speleology club from La Chaux-de-Fonds in the canton of Neuchâtel, Switzerland, under the leadership of Jean-Jacques Miserez, a hydrogeochemist who had the intuition that a cave network might be located in the limestone formation of Siebenhengste. In its early explorations, the Club Jurassien discovered the first three of its 42 entrances. Explorations were later undertaken by many different regional caving clubs: G.S Lausanne, S.S Wallonie, Centre Routier Spéléo de Bruxelles, S.C des Montagnes de Neuchâtel, S.S.S Lausanne, S.G.H. Bern, S.G.H Interlaken, S.G.H. Basel, G.I.P.S, until 1979 when the HRH (Association of Speleologists of the Hohgant Region) was created, which brought together all the people working on the network.
