The earth pyramids of Euseigne are one of the most important geological sights in the Alps and are protected monuments.
The earth cones are 10 to 15 meters high and most of them are protected by a rock lodged on the top.
The cones were created in the end phase of the last Ice Age, about 80,000 to 10,000 years ago.
When the ice retreated, glacier tongues left enormous piles of debris behind, which contained boulders.
Rain and meltwater gradually freed these boulders.
While the water continued to erode and carve out the area surrounding the boulders, these rocks served as protective caps for the soil underneath them, enabling the formation of the well-known natural monuments.
