Geology
The rocky arc of Creux du Van was created in three phases:
- Phase 1: A glacier covered the area of today's Val de Travers around 140,000 years ago (Würm Ice Age). The stream of meltwater eroded material, making a V-shaped valley.
- Phase 2: During subsequent ice ages, other glaciers were created and hollowed out the valley. In warmer periods, the material was eroded by meltwater.
- Phase 3: After the removal of rocks from the fault, erosion of a stronger layer from a different age was much slower.[2]
See cirque for a description of the process forming features like this.
The ground beneath the Creux du Van held permafrost until recently.(permafrost).[3]
