Griesssee Geology Hike – Glacial Lake at Klausenpass
Step into the world of alpine glacial landscapes
This guided geology hike at Klausenpass in the Swiss Alps leads to Griesssee, a true alpine glacial lake shaped by ice and time. Starting near Urnerboden, we explore how glaciers carved high-mountain basins and left behind moraines, debris slopes, and dramatic alpine scenery at nearly 2,000 metres above sea level.
The Glacial Geology of Klausenpass and Griesssee
The Griesssee basin offers an excellent setting for observing high-alpine geomorphology. As the trail climbs from alpine meadows into increasingly rocky terrain, the landscape gradually reveals the powerful natural processes that shaped this mountain environment.
Certain geomorphological features and field interpretations are explained exclusively during the guided tour.
