Pierre à Cambot, Erratic boulder in Vernand-dessous forest, Cheseaux-sur-Lausanne, Switzerland.
Pierre à Cambot is a large erratic boulder made of conglomerate rock located in the Vernand-dessous forest near Cheseaux-sur-Lausanne. The stone occupies a quiet spot in the woods at about 587 meters elevation and can be reached by hiking trails from the nearby communities.
The boulder was transported to this location by the Rhône glacier about 25,000 years ago during the Würm glaciation, starting from the Martigny area. This ancient glacial movement left behind numerous such geological formations across the canton of Vaud.
The boulder stands as a visible reminder of how glaciers shaped the land, and today it draws people interested in understanding this geological past. Locals and visitors treat it as a landmark that tells the story of natural forces at work.
The boulder is easily reached on foot via hiking trails that start from nearby villages and are well marked throughout the walk. The forest terrain is relatively gentle, making it accessible to visitors of most fitness levels.
Only a portion of this stone is visible above ground, as a substantial part may be buried beneath the forest floor. This hidden depth adds to the mystery of how such massive rocks were moved and deposited by ancient glaciers.
