Belgian Cavers Announce Discovery of Two New Cave Systems

August 18, 2013 / Belgium, Europe

The discovery of two significant cave systems has recently been made public by cavers in Belgium.

The caves, both of which exceeded 500 meters (1640 feet) in length, were discovered in Olne, a municipality in the Belgian Province of Liege. Members of the Belgian Union of Speleology, specifically the Speleological Research Group of Comblain-au-Pont (GRSC), were largely responsible for exploring the finds now ranked as the 57th and 63rd longest caves in the country.

The 562 meter (1844 foot) long Michaux Cave was found during the excavation of a building in La Falise, while the other system, the 748 meter (2454 foot) long Grotte-Mine & Grotte de l’Etang de la Villa des Hirondelles, was unearthed after years of digging.

Cavers from Abyss and GRSC began digging in 2002 at a clogged sink some 3.5 meters (12 feet) deep. Pushing the cave through narrow siphons, cavers had their first breakthrough, an area known as the “réseau des mineurs,” in 2005. Years of further exploration resulted in the discovery of “grande suite,” a passage 3 meters wide and 3 to 7 meters high which was filled with a black rock, corals and shell fossils.
