The Big Stone © City Hall Accordingnet

Geological curiosity of more than 500 tons and a height of 5 meters, for a circumference of 30 meters, it is an erratic block.


Result of the cooling of the climate which leads to changes in the glacier, it dates from the last great glaciation of the quaternary during which the Vallée de la Blanche was located at the southern European limit of the valleys encumbered with ice. This one thickens, grows and advances in the valley and carries with it on its way a multitude of blocks. It was deposited 20 years ago.
A marked circuit (6 km from the Town Hall Square) will allow you to discover it.
