Chrüzbachtobel area

The Chrüzbachtobel area near Vättis is a geological window with exposed bedrock. Cave bear bones dating back 53,000 years were discovered here. A complete layer profile from the Triassic to the Tertiary period is visible.

At Vättis, the crystalline rocks of the bedrock (Aar massif) were vaulted upwards. In the area of the dome, glaciers and streams have created the valley, exposing the bedrock in a "geological window". A complete layered profile from the Triassic to the Tertiary period follows above the oldest rocks in the region. At 2427 m.a.s.l. lies the Drachenloch, where more than 53000-year-old cave bear bones and fire remains have been excavated.
