History

Coufin Cave

Oscar Decombaz, on 7, explored up to the wet vault. In 1949, the defusing of the latter allowed Roger Pénelon and Sage to access Gruyère. In 1954, the Cyclops group went up the Mat waterfall (+116 m (381 ft))[a] and stops at the foot of the large waterfall.

  • Grottes de Coufin in circa 1924.

In 1943, Roger Pénelon,

Valence has continued explorations since 1968. The known network develops 29,489 m (96,749 ft) meters for a positive height difference of 411 m (1,348 ft) on 1 January 1997.[4] In 2009 the known development is 32,301 m (105,974 ft).[5]

Description

Soda straw

Like all

underground river forming rimstones and an underground lake from which the Karst spring flows in cascade in the "circus of Choranche". The origin of the underground river is to be found in the Coulmes massif.[7]

Species conservation

The Choranche cave constitutes one of the two sites in France where resides (in captivity) the olm, species of blind salamander adapted to karstic caves. Originally from the caves of the Dinaric Alps of the western Balkans, this species was brought to Choranche as well as to the Clamouse cave as part of a research and project to protect the species.

Notes

  1. ^ In caving, the negative or positive measurements of height levels are defined in relation to at a reference point which is the known entrance to the network, the highest in altitude.
