Overview
- A pilot first reported an unusual unstable area on the north face of the Säntis and helicopter inspections by geologists revealed a deep fissure in the rock beneath the Girenspitz.
- Officials estimate up to 15,000 cubic meters of rock could detach from the affected section of the north face.
- Local and cantonal authorities have closed parts of the Schwägalp area and a pedestrian road below the face while allowing motorized and bicycle traffic to continue on the road.
- A nearby gravel pit halted operations immediately and the cantonal Amt für Raum und Wald has commissioned a geotechnical office to carry out detailed assessments in the coming weeks.
- Authorities have urged hikers to stay on official safe trails; the forthcoming studies will determine if exclusion zones, rock stabilization or controlled detachment are needed and will shape any longer-term restrictions for visitors.
