The dive

The Gelber Brunnen is the second outlet of the same karst system as the Bätterich (Siebenhengste-Hohgant). In March 2013 visibility was ~10 m and the line was in good condition.

Deep (restriction at -68 m) and cold. Same karst system as the Bätterich, where spring snowmelt brings dangerous currents.
