Informations supplémentaires:
These strange geological structures have been formed from material that was carried by glaciers and dumped when they melted They were formed in the last Ice Age approximately 80 000 years ago when the moraines carried by two separate glaciers merged in the middle and the material was compacted under huge pressure from the ice on both sides This made it as hard as concrete Nevertheless it still eroded slowly as a result of the action of the rain However where a larger rock rested on the moraine the rock protected the material beneath it like a cap As a result the moraine on either side gradually eroded away leaving the protective rock cap resting on a tall pillar The pyramids at Euseigne are 10 15 meters 33 50 feet high The protective boulders weigh up to 20 tonnes
