Pyramides d'Euseigne

The Pyramides d'Euseigne are natural earth pillars located in Val d'Herens, formed from glacial deposits topped with protective stones. These columns rise approximately 15 meters and display layered patterns of sediment and rock, with the harder caps preventing erosion of the softer material beneath.

These pillars emerged thousands of years ago when the Eringer glacier retreated from the valley, depositing thick layers of rock and earth. Over millennia, water and weather gradually carved away the softer sediment, leaving only these capped columns as evidence of ancient glacial processes.

These formations have long drawn attention as distinctive landmarks in the valley, sparking curiosity about how nature sculpts rock and soil over time. Visitors stop to observe and photograph these unusual pillars, treating them as windows into the geological forces that shaped the Alps.

A tunnel cuts through the formation, allowing visitors to drive directly through and view these geological structures from the roadway. Parking areas are located on both sides of the route, making it easy to stop and examine the pillars more closely.

The massive boulders perched atop these pillars are often larger than the columns themselves, creating a striking visual balance that seems to defy gravity. Many visitors pause to wonder how these heavy caps remain stable on the narrower structures below.
