Zone Profonde – reloaded

Rolf Siegenthaler

In August 2010 the joint explorers of the Association of Cavers of the Hohgant Region (HRH) was given a new access in the formerly deepest and remotest areas of the huge “Réseau Siebenhengste-Hohgant”. Since then the “Zone Profonde” (ZP) was ‘rediscovered’, rolled up systematically and new discoveries reported in almost every direction.
