The Creux du Van is a natural rocky cirque approximately 1,400 metres (4,600 ft) wide and 150 metres (490 ft) deep, on the north side of Le Soliat,in the Val de Travers district in the Swiss canton of Neuchâtel. A very well known, amphitheatre-shaped natural attraction, it is at the heart of a nature reservation area of 15.5 km2 (6.0 sq mi). It's also on the Federal Inventory of Landscapes and Natural Monuments of Switzerland.
During Winter you can see the Alpine Ibex from near, they are not very afraid of us human beings. And you will be punished if you are too near - the horns are strong ....
Geology (by wikipedia)
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.
The ground beneath the Creux du Van held permafrost until recently.(permafrost).
I will revisit in spring, taking the JuraBike Trail #3 from lake geneva to Basel. The Ibexes have to share the area with Cows in the summer, so it's not so easy to watch them then.
